Nepal SIM Cards, WiFi & Internet Guide 2026: Stay Connected While Trekking

Every trekking season, thousands of trekkers arrive in Kathmandu expecting to stay connected with family, share photos on social media, navigate using GPS apps, and communicate with their trekking teams. Yet most arrive with incomplete or outdated information about Nepal's mobile networks, leading to frustration, wasted money on ineffective SIM cards, or worse—being unreachable during emergencies.

Here's what most trekkers don't realize: the SIM card you buy matters enormously. Ncell dominates in the Everest region with 4G coverage extending to 5,200m, while Nepal Telecom (NTC) provides superior coverage in the Annapurna and Langtang regions. Choose wrong, and you'll have zero signal for days. Choose right, and you can video call home from viewpoints above 4,000m.

Beyond SIM cards, understanding tea house WiFi costs (₨500-1,200 per day), knowing which communication apps work best (Viber is more popular than WhatsApp in Nepal), and having backup options for emergencies can transform your trekking experience from digitally isolated to comfortably connected.

This comprehensive guide cuts through the confusion with verified, practical information covering every aspect of staying connected in Nepal in 2026. We compare Ncell vs Nepal Telecom with actual coverage maps, explain the tourist SIM activation process step-by-step, detail data package options for different trek durations, provide route-specific coverage information (including exact villages where signal drops), cover emerging eSIM options, and explain emergency communication when cellular networks fail.

Ncell vs Nepal Telecom: Complete Comparison

Nepal has two dominant mobile network providers: Ncell (private company, 15+ million subscribers) and Nepal Telecom/NTC (state-owned, 20+ million subscribers). For trekkers, understanding the differences is crucial—your choice directly impacts whether you'll have signal.

Comprehensive Provider Comparison

Detailed Network Analysis

Ncell: The Everest Specialist

Strengths:

• Unmatched Everest coverage: First provider to install 4G at high altitude, with towers at Somare Pari Hill, Dingboche, and near Gorak Shep
• Superior data speeds: Generally faster LTE performance where coverage exists
• Strong Namche Bazaar presence: Excellent signal for multi-day acclimatization stays
• Better customer service: English-speaking support, responsive to issues
• Modern network: Newer infrastructure, better optimization

Weaknesses:

• Poor Annapurna high-altitude coverage: Signal drops significantly above Chhomrong (2,170m)
• Weak Langtang performance: Rarely works past Lama Hotel (2,480m)
• Limited reach in remote regions: Focuses on popular routes, less coverage in off-the-beaten-path areas
• Higher data package costs: Packages generally 10-20% more expensive than NTC for equivalent data

Best for trekkers doing:

• Everest Base Camp (essential choice)
• Everest Three Passes
• Gokyo Lakes
• Any Khumbu/Everest region trek

Real user experience (2025): "I had Ncell for my EBC trek in November 2025. Made a video call to my family from Dingboche (4,410m) with surprisingly good quality. Signal was strong all the way to Gorak Shep. At Everest Base Camp itself, I had intermittent signal but could send WhatsApp messages. Money well spent." — Marcus T., Germany

Nepal Telecom (NTC): The Comprehensive Choice

Strengths:

• Best remote area coverage: Government mandate to provide service in all regions leads to broader tower placement
• Superior Annapurna performance: Works reliably up to Annapurna Base Camp, signals at Thorong La Pass
• Excellent Langtang coverage: Provides signal to Kyanjin Gompa and sometimes beyond
• Better value: Data packages offer 30-50% more data per rupee spent
• Longer validity periods: 28-42 day packages ideal for longer treks
• Free airport SIMs: Tourist SIM cards sometimes offered free at Tribhuvan International Airport

Weaknesses:

• Weaker Everest high-altitude coverage: Doesn't compete with Ncell above Tengboche in Khumbu
• Slower customer service: Government bureaucracy can make issue resolution frustrating
• Older infrastructure in some areas: Some towers haven't been upgraded to 4G
• Inconsistent performance: Service quality varies more than Ncell's

Best for trekkers doing:

• Annapurna Base Camp (essential choice)
• Annapurna Circuit (essential choice)
• Langtang Valley (essential choice)
• Manaslu Circuit
• Gosainkunda
• Remote region treks

Real user experience (2025): "NTC saved me on the Annapurna Circuit. While my friend with Ncell had no signal above Chhomrong, I had reliable 3G all the way to Deurali and even got some signal at ABC. Cost less than Ncell too. Highly recommend for Annapurna region." — Sarah M., Australia

Smart Cell: The Third Option

Smart Cell (also called Smart Telecom or STel) is Nepal's third mobile provider with limited but growing coverage.

Pros:

• Competitive pricing
• Good urban coverage in Kathmandu and Pokhara
• Newer network technology in covered areas

Cons:

• Virtually no trekking route coverage
• Limited tower infrastructure outside major cities
• Smaller subscriber base means less network priority

Verdict: Skip for trekking purposes. Smart Cell is fine for Kathmandu/Pokhara stays but useless on trails.

The Dual SIM Strategy (Recommended)

Why carry both Ncell and NTC:

1. Complementary coverage: Where one fails, the other often works
2. Minimal cost: Total investment under $2 for both SIM cards
3. Emergency redundancy: If one network goes down, you have backup
4. Flexibility: Use whichever has better signal at each location
5. No downside: Modern phones support dual SIM or you can swap SIMs

How to implement:

• Dual SIM phone: Install Ncell in slot 1 (primary data), NTC in slot 2
• Single SIM phone: Carry both SIMs, check both each morning, use whichever has better signal that day
• Data strategy: Load primary data package on Ncell (if Everest) or NTC (if Annapurna), use the other for calls/SMS backup

Where to Buy Tourist SIM Cards

You have three main options for purchasing tourist SIM cards in Nepal: Tribhuvan International Airport (most convenient), shops in Thamel/Pokhara (more options), or outlets in trekking villages (limited availability). Each has advantages and trade-offs.

Option 1: Tribhuvan International Airport (Recommended)

Location: Just outside the baggage claim area and customs exit, in the arrivals hall. Both Ncell and Nepal Telecom have clearly marked official counters.

Hours:

• Ncell counter: 9:00 AM - 5:30 PM daily (NOT 24 hours)
• NTC counter: 9:00 AM - 5:30 PM daily (similar hours)
• Important: If you arrive early morning (before 9 AM) or late evening (after 6 PM), counters will be closed. You'll need to wait or purchase in the city.

What to expect:

1. Walk out through customs with your luggage
2. Look right—you'll see mobile operator counters
3. Join queue (usually 5-10 people, moves quickly)
4. Present passport, visa page, and one passport photo
5. Staff completes registration form (you sign)
6. SIM card activated in 10-15 minutes
7. They'll help you install SIM and test the connection
8. You can purchase data packages immediately

Advantages:

• Bring a pen to sign forms
• Ask for both Ncell and NTC SIMs while you're there
• Request staff to check signal strength before you leave counter
• Get their WhatsApp/phone number for support if needed

Option 2: Thamel (Kathmandu Tourist District)

Location: Thamel, Kathmandu's tourist hub, has dozens of mobile shops and official Ncell/NTC centers. Official centers are more reliable than small shops.

Finding official centers:

• Search Google Maps for "Ncell Center Thamel" or "Nepal Telecom Thamel"
• Look for official signage and branding
• Ask your hotel/hostel for nearest authorized dealer
• Major centers are on main Thamel roads, easy to find

Hours:

• Official centers: 9:00 AM - 6:00 PM Sunday-Friday
• Small shops: 8:00 AM - 8:00 PM daily (more flexible)
• Saturday: Some centers closed or limited hours (Nepal's weekly holiday)

What to expect:

1. Visit official Ncell or NTC center
2. Present passport, visa, passport photo
3. Complete registration form
4. Pay for SIM and selected data package
5. Activation takes 10-20 minutes
6. Staff configure phone and test

Advantages:

• Wider package selection: Full range of data packages available
• Can shop around: Compare Ncell vs NTC in detail, ask questions
• Flexible timing: Can purchase when convenient during Kathmandu stay
• Hotel assistance: Many hotels help with registration and translation

Disadvantages:

• Takes more time: Need to dedicate 30-60 minutes to find shop, register, activate
• Saturday closures: Official centers often closed on Saturdays
• Language barriers: Small shops may have limited English
• Risk of unofficial dealers: Some shops aren't authorized, leading to registration problems
• Less convenient: Must navigate Thamel streets with luggage or on separate trip

Cost in Thamel:

• Often ₨50-100 cheaper than airport for data packages
• More promotional offers
• Bundle deals (SIM + data package) sometimes available

Which shops to trust:

• Official Ncell Centers: Look for bright blue Ncell branding
• Official NTC Centers: Look for red/blue Nepal Telecom signage
• Authorized dealers: Display official authorization certificates
• Avoid: Small mobile shops without official branding unless hotel-recommended

Option 3: Pokhara Mobile Shops

When relevant: If you're flying directly to Pokhara to start Annapurna treks, or if you forgot to buy in Kathmandu.

Location: Multiple official Ncell and NTC centers around Lakeside (tourist area), near the airport.

Process: Identical to Thamel—passport, photo, registration, activation in 15-20 minutes.

Advantages:

• Convenient if starting trek from Pokhara
• Less crowded than Kathmandu options
• Staff experienced with trekkers heading to Annapurna

Note: Same hours and closure patterns as Thamel (closed Saturdays at official centers).

Option 4: Mobile Shops in Trekking Villages

Available in major trekking towns:

• Lukla: Ncell shop near airport (expensive, limited packages)

WiFi at Tea Houses

Nearly all tea houses on major trekking routes now offer WiFi service—but it's slow, expensive, and unreliable compared to Western standards. Understanding how tea house WiFi works helps you decide whether to use mobile data, pay for WiFi, or plan for offline connectivity.

How Tea House WiFi Works

Technology:

• Most tea houses use mobile broadband connections (Ncell or NTC 3G/4G)
• A single mobile connection is shared among all guests via WiFi router
• Not traditional broadband—essentially hotspot from mobile SIM card
• Limited bandwidth split among 10-30 guests

Why it's slow:

• Single 3G/4G connection divided among many users
• At high altitude, mobile signals are already weak
• Solar power limitations (routers turned off at night to conserve battery)
• Weather affects signal quality
• Peak usage times (evening) create congestion

WiFi Costs by Altitude

Prices increase with altitude due to infrastructure challenges and limited competition:

Lower altitudes (2,000-3,000m):

• Cost: ₨300-500 per 24 hours ($2.20-$3.60)
• Examples: Lukla, Phakding, Monjo, lower Annapurna villages
• Speed: 2-5 Mbps when working well
• Reliability: Generally good

Mid altitudes (3,000-4,000m):

• Cost: ₨500-800 per 24 hours ($3.60-$5.80)
• Examples: Namche Bazaar, Tengboche, Chhomrong, Manang
• Speed: 1-3 Mbps, often slower
• Reliability: Moderate, depends on solar power and weather

High altitudes (4,000-4,500m):

• Cost: ₨800-1,200 per 24 hours ($5.80-$8.70)
• Examples: Dingboche, Deurali (Annapurna), Lobuche
• Speed: 0.5-2 Mbps, painfully slow
• Reliability: Poor, frequent disconnections

Very high altitudes (4,500m+):

• Cost: ₨1,000-1,500 per 24 hours ($7.25-$10.90)
• Examples: Gorak Shep, Annapurna Base Camp lodges
• Speed: <1 Mbps, barely functional
• Reliability: Very poor, may not work for hours

WiFi Card System

How purchasing works:

1. Request WiFi card from tea house staff
2. Pay ₨400-1,200 depending on location
3. Receive card with:
   • WiFi network name (SSID)
   • Password
   • Username/code for login portal
   • Validity period (usually 24 hours)

Typical card pricing:

• 24-hour card: ₨400-1,000 (most common)
• 48-hour card: ₨800-1,500 (10-20% discount vs buying two 24-hour cards)
• Per-hour cards: ₨100-300 (available in some places, poor value)

Activation:

1. Connect to WiFi network
2. Open browser (auto-redirects to login portal)
3. Enter username/password from card
4. Accept terms
5. Connected (timer starts)

Multi-device:

• Most systems allow only ONE device connected per card
• Some tea houses allow 2 devices but significantly slower
• Sharing one card among multiple travelers doesn't work well

WiFi Speed Reality Check

What you CAN do:

• ✅ Send WhatsApp text messages
• ✅ Send compressed photos (wait 2-5 minutes per photo)
• ✅ Check email (text only)
• ✅ Basic web browsing (very slow page loads)
• ✅ Update Facebook/Instagram text posts
• ✅ Check weather forecasts

What you CAN'T realistically do:

• ❌ Video calls (too slow, constant buffering)
• ❌ Stream music or podcasts
• ❌ Watch YouTube videos
• ❌ Upload high-resolution photos (would take 30+ minutes each)
• ❌ Video streaming of any kind
• ❌ Download apps or updates
• ❌ Load image-heavy websites

Typical speeds by location:

| Location | Expected Speed | Reality | |----------|---------------|---------| | Namche Bazaar | 2-5 Mbps | Can upload photos, slow but functional | | Tengboche | 1-3 Mbps | Messaging works, photos take time | | Dingboche | 0.5-2 Mbps | Very slow, messages only | | Lobuche | <1 Mbps | Barely works, frustrating | | Gorak Shep | <0.5 Mbps | Essentially non-functional for anything but text |

Mobile Data vs Tea House WiFi

When to use mobile data (your SIM card):

• ✅ Lower and mid altitudes where signal is good
• ✅ Time-sensitive communication
• ✅ Uploading photos to social media
• ✅ Video calls
• ✅ When you need reliable connection
• ✅ More cost-effective if you have 20-30GB package

When to use tea house WiFi:

• ✅ When your mobile data is running low
• ✅ No mobile signal in that location
• ✅ Staying multiple nights and want occasional connectivity
• ✅ Light usage (checking email, sending messages)
• ✅ Sharing costs with trekking partners (one person buys WiFi, shares phone hotspot)

Cost comparison (14-day trek):

• Mobile data only: 20-30GB package = ₨700-1,200 ($5-$9) total
• Tea house WiFi only: 7-10 nights × ₨600 average = ₨4,200-6,000 ($30-$45) total
• Hybrid approach: Mobile data + 2-3 WiFi cards in dead zones = ₨1,500-2,500 ($11-$18) total

Verdict: Mobile data packages are far more cost-effective and reliable. Use tea house WiFi only as backup when mobile signal is unavailable.

Best Practices for Tea House WiFi

Compress photos before uploading:

• Use apps like "Photo Compress" or "Reduce Photo Size"
• Reduce resolution to 1080p or lower
• Can reduce upload time from 15 minutes to 2 minutes per photo

Use WiFi-optimized apps:

• WhatsApp and Viber compress data automatically
• Use "Data Saver" modes in browsers
• Disable auto-play videos on social media apps

Upload during off-peak hours:

• Early morning (6-8 AM): Fewer users, better speeds
• Mid-afternoon (2-4 PM): Moderate usage
• Avoid: Evening (6-9 PM): Everyone using WiFi, painfully slow

Cache content when you have good signal:

• Download offline maps in Kathmandu or Namche
• Save articles for offline reading
• Download podcasts/music before trek
• Pre-download entertainment

Be patient:

• WiFi at 4,500m is never going to be fast
• Budget 30-60 minutes for uploading 5-10 photos
• Don't expect real-time communication

WiFi Availability by Trek

100% WiFi availability:

• Everest Base Camp (every tea house offers WiFi)
• Annapurna Base Camp (every tea house offers WiFi)
• Annapurna Circuit (all major stops)

90%+ WiFi availability:

• Langtang Valley (most tea houses)
• Gokyo Lakes (major villages)
• Poon Hill circuit

50-80% WiFi availability:

• Manaslu Circuit (larger villages only)
• Upper Mustang (main settlements)

Limited WiFi (<50%):

• Dolpo region
• Kanchenjunga
• Makalu Base Camp
• Very remote treks

eSIM Options for 2026

eSIM (embedded SIM) technology is increasingly available for Nepal in 2026, offering a convenient alternative to physical SIM cards. However, eSIMs have significant trade-offs that make physical SIM cards still the better choice for most trekkers.

What is eSIM?

eSIM basics:

• Digital SIM card downloaded to your phone
• No physical card needed
• Activated through app or QR code
• Supported by newer iPhones (XS/XR and later) and many Android phones

How it works:

1. Purchase eSIM online before traveling
2. Receive QR code or activation code via email
3. Scan code in phone settings
4. eSIM activates and connects to Nepal network
5. Ready to use when you land in Nepal

Major eSIM Providers for Nepal

1. Airalo (Uses Ncell Network)

Overview:

• Most popular eSIM provider globally
• Partners with Ncell in Nepal

• Hotspot allowed (500MB limit)

Cons:

• Extremely expensive ($47-288 vs $5-10 local SIM)
• "Unlimited" has fair usage caps
• Data-only (no calls/SMS)
• Hotspot severely limited (defeats unlimited claim)

Best for:

• Expense-account travelers
• Those who absolutely must have unlimited data
• Short business trips to Kathmandu/Pokhara

3. Nomad (Multiple Network Options)

Overview:

• Growing eSIM provider
• Offers both Ncell and NTC eSIM options for Nepal

Plans:

• 1GB / 7 days: $5 USD
• 3GB / 30 days: $12 USD
• 5GB / 30 days: $18 USD

Similar to Airalo in pricing and features.

Ncell and NTC Official eSIMs

Both Nepali carriers now offer eSIM:

Ncell eSIM:

• Available but primarily for residents
• Tourists can request but process is complicated
• Not easily purchasable online
• Same pricing as physical SIM once activated

Nepal Telecom eSIM:

• Officially available since 2024
• Can activate at NTC offices in Kathmandu
• Requires same documents as physical SIM (passport, photo)
• Same pricing structure as physical SIM
• Activation process: dial *1415# to request eSIM conversion

Problem: Both require in-person registration in Nepal, defeating the convenience of eSIM.

eSIM vs Physical SIM Card: Honest Comparison

When eSIM Makes Sense

eSIM is worth considering if:

• ✅ You're only visiting Kathmandu/Pokhara (not trekking)
• ✅ Very short trip (3-5 days)
• ✅ Money is no concern (expense account, business trip)
• ✅ You absolutely cannot spend 15 minutes at airport
• ✅ You need instant connectivity the moment you land
• ✅ Your home SIM must stay in phone (can't swap)

Physical SIM is better if:

• ✅ You're trekking (need maximum value and flexibility)
• ✅ Staying 7+ days
• ✅ Want to make actual phone calls
• ✅ Need emergency calling capability
• ✅ Want 5-10x better value
• ✅ Can spare 15 minutes at airport for registration

My Recommendation: Physical SIM Card

For 90% of trekkers, physical SIM cards remain the superior choice:

1. Cost: $5-10 vs $26-66 for similar usage
2. Value: 5-10x more data per dollar spent
3. Flexibility: Easy to recharge, many package options
4. Emergency capability: Can make calls to rescue services, hotels, guides
5. Local integration: Get local phone number for booking, communication

The 15 minutes spent at the airport buying and activating a physical SIM card saves you $20-55 and provides significantly better functionality.

eSIM makes sense for business travelers in Kathmandu for 2-3 days who value convenience over cost. For trekkers, the economics strongly favor physical SIM cards.

Communication Apps That Work

In 2026, Nepal's social media landscape has shifted. Understanding which apps work, which are blocked, and which are most popular among locals is crucial for staying connected.

Current App Status (2026)

Blocked/Restricted Apps:

• WhatsApp: Blocked since 2025 due to government regulations requiring social media registration
• Facebook: Blocked for unregistered platforms
• Instagram: Blocked for unregistered platforms

Working Apps:

• Viber: ✅ Fully functional, most popular in Nepal
• Telegram: ✅ Working, growing usage
• Signal: ✅ Working, privacy-focused option
• WeChat: ✅ Working
• X (Twitter): ✅ Registered and functional
• Email: ✅ Always works

Viber: The Essential App for Nepal

Why Viber dominates in Nepal:

• Over 10 million active users in Nepal
• Registered with Nepal government (not blocked)
• All hotels, trekking agencies, and guides use Viber
• Tea houses communicate via Viber
• Free voice calls, video calls, and messaging over data

Download before traveling:

• Get Viber before arriving in Nepal
• Set up account with your home number
• Once in Nepal, works with Nepal SIM data

Features for trekkers:

• Voice calls (good quality on 3G)
• Video calls (works on 4G, pixelated on 3G)
• Group chats with trekking groups
• Photo/video sharing (compresses automatically)
• Voice messages (great for slow connections)
• Location sharing
• Works offline (messages queue and send when signal returns)

How locals use it:

• Tea house bookings via Viber
• Guide communication before/during trek
• Hotel reservations
• Emergency contact with trekking agencies

Alternative Communication Apps

Telegram:

• Good privacy, encrypted messaging
• Works well in Nepal
• Less popular than Viber among locals
• Good for personal communication with friends/family
• Channels and groups useful for travel tips

Signal:

• Best privacy and encryption
• Works in Nepal
• Very few locals use it
• Good for sensitive communications
• Lightweight, works on slow connections

Email:

• Always works (web-based or app)
• Reliable for non-urgent communication
• Good for sending detailed trip reports
• Works on very slow connections (text-only)

FaceTime (iPhone/Mac users):

• Works over data connections
• Requires decent 4G signal (lower altitudes only)
• Good quality when it works
• Only works with other Apple users

Skype:

• Still works in Nepal
• Can call regular phone numbers (SkypeOut)
• Heavy data usage
• Quality inconsistent on 3G

VoIP Calling Strategy

For calling home:

1. Best: Viber-to-Viber calls (free, good quality on 3G/4G)
2. Good: Telegram calls (free, encrypted)
3. Okay: Skype (costs money for regular phones)
4. Data-heavy: FaceTime (Apple only, requires 4G)

For calling within Nepal:

1. Best: Regular phone call (your Nepal SIM, cheap rates)
2. Good: Viber-to-Viber (if they have Viber)
3. Emergency: Use tea house phone (expensive but reliable)

For calling internationally to regular phones:

1. Buy international calling package on Nepal SIM (cheapest)
2. Skype credit (moderate cost)
3. Avoid: International roaming from home SIM (extremely expensive)

Communication App Data Usage

Understanding data consumption helps plan package size:

Viber:

• Text messages: <1 KB per message (negligible)
• Voice call: 500 KB per minute (~30 MB per hour)
• Video call: 4-8 MB per minute (~240-480 MB per hour)
• Photo sharing: 200-500 KB per compressed photo

Telegram:

• Similar to Viber
• Slightly more efficient compression
• Voice calls: 400-600 KB per minute

Email:

• Text-only: <10 KB per email
• With photos: 500KB-5MB depending on attachments

Social media (when not blocked):

• Instagram scrolling: 100-200 MB per hour
• Facebook scrolling: 150-300 MB per hour
• Uploading 1 photo: 1-3 MB compressed, 5-15 MB original

Dealing with App Blocks

If WhatsApp/Facebook are essential for you:

Option 1: VPN (Variable Success)

• Some VPNs work in Nepal, allowing access to blocked apps
• ExpressVPN and NordVPN reported to work (as of early 2026)
• Problem: VPNs consume extra data (20-30% overhead)
• Problem: VPNs slow already-slow connections
• Problem: May not work reliably at altitude

Option 2: Accept the Block and Adapt

• Download Viber and Telegram before traveling
• Inform family/friends you'll use alternative apps
• Embrace the opportunity to use less social media
• Many trekkers find it refreshing to be off Facebook/Instagram

Option 3: Scheduled Check-ins

• Use Viber for regular family updates
• Save Facebook/Instagram updates for when you return
• Email detailed trip reports
• Post retrospectively after trek

Practical reality: Most trekkers adjust quickly to Viber and enjoy the break from social media. Connectivity on treks is limited anyway—focus on the mountains, not the apps.

Emergency Communication

When cell service fails or you're in a genuine emergency, having backup communication plans is critical. Understanding emergency systems in Nepal can save lives.

Emergency Phone Numbers in Nepal

Critical emergency numbers (work from any phone):

• Nepal Police: 100
• Tourist Police: 1144 (English-speaking, specifically for tourists)
• Ambulance: 102
• Fire Brigade: 101

Helicopter Rescue Coordination:

• Himalayan Rescue Association (HRA): +977-1-4440292 / +977-985-1071956
• Mountain Rescue: +977-1-4440146
• Simrik Air Rescue: +977-1-4499933
• Fishtail Air Rescue: +977-1-4465888

Your Embassy (save these numbers):

• Should be saved in phone before trekking
• Can assist with emergencies, but don't handle medical evacuation
• Useful for passport issues, serious legal problems

When Cell Service Fails

Scenarios where mobile coverage isn't available:

1. High altitude dead zones (above 5,000m in many areas)
2. Weather-related signal loss (heavy clouds, storms)
3. Remote trek regions (Manaslu high camps, Dolpo, etc.)
4. SIM card failure or loss
5. Phone battery dead with no charging

Backup communication methods:

1. Your Trekking Guide's Satellite Phone

• All reputable trekking agencies equip guides with sat phones for emergencies
• Thuraya is most common in Nepal
• Works anywhere with clear sky view
• For true emergencies only (calls cost $2-5 per minute)

2. Tea House Satellite Phones

• Some high-altitude tea houses have sat phones
• Available for guest emergencies
• Expensive ($5-10 per minute)
• Usually Thuraya or Iridium systems

3. Ham Radio Networks

• Some remote lodges have ham radio
• Can relay emergency messages
• Requires operator at both ends
• Backup option when everything else fails

4. Word-of-Mouth Relay

• In extreme emergency with no comms, send message with descending trekkers
• Ask them to call rescue services when they reach signal
• Write down critical information (location, condition, phone number for callback)
• Old school but has saved lives

Helicopter Rescue Process

Understanding how rescue actually works helps you respond appropriately in emergencies.

Step 1: Assess the Situation

• Is this a true emergency requiring evacuation?
• Altitude sickness (HAPE/HACE): YES, immediate evacuation
• Severe injury preventing descent: YES
• Broken bone but can walk down slowly: Maybe not—assess with guide
• Mild altitude sickness: NO—descend on foot

Step 2: Contact Rescue Services

• First: Contact your trek guide (they coordinate rescue)
• Second: Call your travel insurance emergency line
• Third: Contact helicopter rescue company directly if first two fail
• Provide: Exact location (GPS coordinates if possible), nature of emergency, patient condition, weather conditions

Step 3: Insurance Authorization

• Most insurance companies must authorize evacuation
• Provide policy number, patient name, emergency details
• Insurance contacts helicopter company directly
• Critical: Without insurance, YOU must guarantee payment ($3,500-6,500)

Step 4: Prepare for Pickup

• Move to open area visible from air
• Mark landing zone (rocks in "H" shape, brightly colored items)
• Have someone wave to helicopter
• Secure all loose items (rotor wash is intense)
• Stay clear until helicopter lands
• Follow pilot instructions exactly

Step 5: Evacuation and Treatment

• Helicopter flies to Kathmandu (45-90 minutes depending on location)
• Patient taken to CIWEC, Norvic, or Grande Hospital
• Treatment begins
• Family notified

Rescue cost realities (2026):

• Lukla to Kathmandu: $2,500-3,500
• Namche to Kathmandu: $3,000-4,000
• Dingboche/Lobuche to Kathmandu: $4,500-5,500
• Gorak Shep/EBC to Kathmandu: $5,000-6,500
• Remote regions (Manaslu, Makalu): $6,000-8,000+

Payment process:

• Insurance pays directly (best case)
• You pay, insurance reimburses later (common)
• You pay, insurance denies claim (worst case—why you need proper insurance)

Weather delays:

• Helicopters can't fly in bad weather (clouds, wind, snow)
• May need to wait hours or days for weather window
• This is why early evacuation decision-making is critical
• Don't wait until you're dying to call for rescue

SMS When Voice Calls Fail

Text messages work better than calls in weak signal:

• SMS requires far less signal strength than voice
• Messages queue and send when brief signal appears
• Can take 5-60 minutes to send in weak coverage areas

Emergency SMS strategy:

• Keep messages SHORT (160 characters or less)
• Include critical info: Location, problem, action needed
• Send to multiple people (guide, family, emergency contact)
• Don't expect immediate reply

Example emergency SMS: "At Lobuche lodge. Severe altitude sickness. Calling helicopter. Don't worry, insured. Will contact when in KTM. - [Your name]"

GPS Emergency Beacons

Personal Locator Beacons (PLB):

• Satellite-based SOS devices
• Garmin inReach: Most popular for trekkers
• SPOT Gen4: Alternative option
• Work anywhere on earth (satellite connection)

Garmin inReach features:

• Two-way text messaging via satellite
• SOS button alerts rescue services with your GPS location
• Weather forecasts
• Works when all else fails

Cost:

• Device: $350-450 purchase (can rent in Kathmandu for $10-15/day)
• Service: $15-65/month depending on plan
• Worth it for: Remote treks, solo trekkers, peace of mind

Most trekkers don't need PLB for standard routes (EBC, ABC): Guide-equipped satellite phones and good mobile coverage make them unnecessary. But for Dolpo, Makalu, Kanchenjunga, or solo remote trekking, they're valuable insurance.

Charging Stations on Trail

Your communication devices are useless without power. Understanding charging availability, costs, and strategies is critical.

Charging Availability by Altitude

Lower altitudes (2,000-3,000m):

• Power source: Hydroelectric (reliable grid power)
• Availability: Most tea houses offer free charging
• Socket location: Often in rooms or dining hall
• Restrictions: Few restrictions, charge overnight okay
• Examples: Lukla, Phakding, Monjo, Jorsale, lower Annapurna villages

Mid altitudes (3,000-4,000m):

• Power source: Mix of hydroelectric and solar
• Availability: Charging available but now costs money
• Socket location: Dining hall only (not in rooms)
• Cost: ₨200-400 per full charge
• Restrictions: Limited hours (usually 6 PM - 9 PM)
• Examples: Namche Bazaar, Tengboche, Chhomrong, Manang

High altitudes (4,000-5,000m):

• Power source: Primarily solar (weather-dependent)
• Availability: Limited, expensive
• Socket location: Dining hall only, supervised
• Cost: ₨400-800 per full charge
• Restrictions: Strict time limits, cloudyday = no charging
• Examples: Dingboche, Deurali (ABC), Lobuche, Thorong Phedi

Very high altitudes (5,000m+):

• Power source: Solar only (very limited)
• Availability: May not be available at all
• Socket location: Dining hall, limited outlets
• Cost: ₨600-1,000 per full charge (if available)
• Restrictions: First-come first-served, may be refused

Note: Prices increase during peak season when demand is high and during cloudy weather when solar generation is limited.

Solar Power Reality

How solar charging works:

• Tea houses have solar panels on roofs
• Solar charges batteries during day
• Batteries provide power in evening
• Cloudy days = reduced charging capacity

Solar power limitations:

• Weather-dependent: Cloudy or snowy days drastically reduce power
• Limited capacity: Tea house may refuse charging if batteries low
• First-come, first-served: Early requesters get priority
• Time restrictions: Usually only 2-4 hours evening charging
• No overnight charging: Power too limited

Multi-day cloudy weather scenario:

• 3-4 cloudy days in a row (common in monsoon/winter)
• Solar batteries completely depleted
• Tea house may not offer any charging
• Your devices die if you don't have backup power

Charging Strategies

Strategy 1: Maximize Lower Altitude Charging (Recommended)

1. Fully charge all devices in Kathmandu/Lukla before trek
2. Charge power bank + all devices at Namche Bazaar (spend 3 days there, cheap power)
3. Use power bank above Namche
4. Only pay for tea house charging in emergencies
5. Charge power bank again at Namche on return

Strategy 2: Regular Tea House Charging

1. Budget ₨200-600 per day for device charging
2. Request charging when you arrive at tea house
3. Monitor charging (devices sometimes "disappear" or get unplugged for others)
4. Accept charging limitations at high altitude

Strategy 3: Ultra-Minimal Power

1. Turn off phone most of the time (use for photos only)
2. Airplane mode except when actively using
3. One charge every 3-4 days
4. Requires discipline but minimizes charging costs

Device Charging Tips

Maximize battery life:

• Airplane mode: Saves 50-70% battery when not actively using phone
• Low power mode: (iPhone) or Battery Saver (Android)
• Reduce screen brightness: Biggest battery drain
• Close background apps: Especially social media
• Turn off location services: GPS drains battery fast
• Disable automatic updates: App updates eat battery
• Cold temperature management: Keep phone warm (batteries die faster in cold)

What to bring:

• Power bank: 20,000-30,000mAh recommended
• Charging cables: Bring 2 (one backup in case one breaks)
• Universal adapter: Nepal uses Type C/D/M plugs (European 2-pin works)
• Multi-port charger: Charge phone + power bank + camera simultaneously
• Solar charger (optional): 10-20W panel, charge power bank during rest days

Charging priority:

• Priority 1: Phone (communication, navigation, emergency)
• Priority 2: Headlamp (safety at night)
• Priority 3: Camera/GoPro (memories)
• Priority 4: Tablet/e-reader (entertainment)
• Priority 5: Bluetooth speaker, other luxuries

Power Bank Recommendations

Capacity needed:

• 10,000mAh: 2-3 smartphone charges, sufficient for short treks (5-7 days)
• 20,000mAh: 4-6 smartphone charges, ideal for 14-day treks (recommended)
• 30,000mAh: 6-9 smartphone charges, excellent for 21+ day treks or multiple devices

Top models for trekking:

• Anker PowerCore 20100: Reliable, affordable ($35-50)
• RAVPower 26800: High capacity, good for long treks ($45-60)
• Goal Zero Flip 36: Durable outdoor design ($70-80)

Where to charge power bank:

• Kathmandu hotel (free, overnight)
• Lukla tea houses (free or cheap)
• Namche Bazaar: Best place (good power, relatively cheap ₨200-300, spend 3 days)
• Lower altitude villages on descent

Power bank + solar panel combo:

• Attach solar panel to backpack while hiking
• Trickle-charges power bank during 5-7 hours walking
• Adds 20-30% charge per day (sunshine dependent)
• Useful but not essential (heavy, expensive)

Satellite Communication Options

For the most remote treks or those who must have guaranteed communication regardless of cellular coverage, satellite systems provide reliable backup.

Thuraya Satellite Phones

What is Thuraya:

• Satellite phone system covering Asia, Middle East, Europe, Africa
• Works anywhere with clear view of sky
• Most common sat phone system in Nepal

How it works:

• Handheld phone (looks like bulky 1990s cell phone)
• Extends antenna
• Connects to satellite (requires 1-2 minutes)
• Makes voice calls to any number worldwide

Availability in Nepal:

• Most trekking agencies equip guides with Thuraya phones
• Some high-altitude tea houses have Thuraya for guest emergencies
• Can be rented in Kathmandu ($10-15/day + usage fees)

Costs:

• Rental: $10-15 per day
• Calls: $1.50-$3 per minute
• Receiving calls: $0.75-$1.50 per minute
• SMS: $0.50-$1 per message

When guides use Thuraya:

• Medical emergencies requiring helicopter evacuation
• Severe weather requiring plan changes
• Lost trekkers/search operations
• Daily check-ins with agency (on some tours)

Can tourists rent Thuraya phones?

• Yes, from some Kathmandu trekking agencies
• Requires large deposit ($200-500)
• You pay for all usage
• Must return in good condition

Worth it for tourists?

• No for standard EBC/ABC treks (guides have them, good cellular coverage)
• Maybe for very remote treks (Dolpo, Makalu, Upper Mustang)
• Yes if you absolutely must have guaranteed daily communication

Iridium Satellite Phones

Iridium network:

• Global coverage (works literally anywhere on Earth, including poles)
• More satellites than Thuraya (66 vs 2), better reliability
• More expensive than Thuraya

Costs:

• Rental: $15-25 per day
• Calls: $1.50-$3 per minute
• Less common in Nepal than Thuraya

Who uses Iridium:

• High-altitude expeditions (Everest summit climbs)
• Extremely remote treks
• Professional filmmakers/journalists
• Overkill for standard trekking

Garmin inReach: The Modern Solution

What is Garmin inReach:

• Handheld GPS device with two-way satellite messaging
• Text-message based (not voice calls)
• SOS emergency beacon
• Weather forecasts
• GPS tracking and navigation

Models:

• inReach Mini 2: Compact, pairs with smartphone ($380)
• inReach Explorer+: Built-in maps and screen ($450)
• inReach Messenger: Latest model with full messaging ($300)

How it works:

1. Device connects to Iridium satellite network
2. Send/receive text messages up to 160 characters
3. Preset messages or custom messages
4. Loved ones see your GPS location on map
5. SOS button alerts rescue services with exact coordinates

Service plans (2026):

• Safety: $15/month (10 messages/month, unlimited SOS)
• Recreation: $35/month (unlimited messages, tracking, weather)
• Expedition: $65/month (unlimited everything, enhanced features)
• Can suspend service when not using (only pay for months you need)

Advantages over satellite phones:

• Lightweight (100g vs 300g+ for sat phone)
• Much longer battery life (50+ hours inReach vs 4-6 hours sat phone)
• More affordable ($35/month vs $10-15/day rental + usage)
• Two-way messaging more efficient than calls
• Built-in GPS and maps
• Family can track your location in real-time

Disadvantages:

• Text only (no voice calls)
• Requires typing (slow on small device)
• Initial device cost ($300-450)

Is Garmin inReach worth it?

Yes, if you:

• Trek remote routes (Dolpo, Makalu, Kanchenjunga)
• Trek solo without guide
• Want family to track your location daily
• Do multiple treks per year (device pays for itself)
• Value peace of mind and safety backup

No, if you:

• Only doing standard EBC/ABC with guide (guide has sat phone, good cellular coverage)
• One-time trek (rental makes more sense)
• Budget-conscious (adds $100-150 to trip cost)

Starlink in Nepal

Current status (2026):

• Starlink satellite internet is NOT legally authorized in Nepal
• Nepal Telecommunications Authority prohibits unauthorized satellite internet
• Using Starlink violates Nepal's Telecommunications Act

Despite prohibition:

• Some lodges in Everest region allegedly using Starlink illegally
• Nepal government threatens penalties
• Tourist use not recommended (legal risk)

Future possibility:

• Elon Musk expressed interest in providing Starlink to Everest region
• No license granted as of 2026
• May become legal in future, but not currently

Verdict: Don't plan on Starlink access in Nepal. Stick with legal options (Ncell/NTC mobile networks, Thuraya, Garmin inReach).

Tips for Maximizing Connectivity

Strategic use of available connectivity options helps you stay connected without breaking the bank or constantly battling slow networks.

Pre-Trek Preparation

Before leaving home:

1. ✅ Download Viber and test with friends/family
2. ✅ Unlock your phone (contact carrier if locked)
3. ✅ Download offline maps:
   • Maps.me (full Nepal map, free)
   • Google Maps offline areas (Khumbu, Annapurna regions)
   • Trekking-specific apps (Himalayan Routes, VisitNepal)
4. ✅ Download entertainment:
   • Spotify/Apple Music: download playlists for offline
   • Netflix: download shows/movies
   • Podcasts: download 20+ episodes
   • Kindle books/audiobooks
5. ✅ Save emergency numbers in phone contacts + screenshot
6. ✅ Print backup info: Hotel addresses, flight details, embassy numbers

In Kathmandu before trek:

1. ✅ Buy SIM cards at airport (or next day in Thamel)
2. ✅ Purchase full data package (don't wait until on trail)
3. ✅ Fully charge all devices + power bank before departing
4. ✅ Test SIM card and data connection (make test call, load webpage)
5. ✅ Configure messaging apps (Viber, Telegram) with Nepal number
6. ✅ Email yourself important info: Trekking permit numbers, insurance details, key contacts
7. ✅ Update family/friends: "I'm in Nepal, this is my local number: +977-XXX"

On-Trail Connectivity Strategy

Morning routine (where there's signal):

1. Check signal strength upon waking
2. Send quick update messages to family (5 minutes)
3. Check weather forecast
4. Review emails (don't respond to non-urgent)
5. Total time: 10-15 minutes
6. Put phone in airplane mode for rest of day

Evening connectivity window:

1. Arrive at tea house (3-4 PM)
2. Check mobile signal, connect to network
3. Send photo updates (compress photos first: 20-30 minutes)
4. Make video call if good 4G signal (10-15 minutes)
5. Check important messages/emails
6. Upload Instagram story if desired (10 minutes)
7. Total time: 40-60 minutes
8. Disconnect, enjoy tea house socialization

Benefits of scheduled connectivity:

• Doesn't consume your entire day
• Family knows when to expect updates
• Reduces stress of constant connectivity checking
• More present and mindful during hiking
• Preserves battery life

Battery Management

Cold weather battery protection:

• Keep phone in inside jacket pocket (body warmth)
• Don't leave phone in cold tent/room overnight
• Batteries lose 20-40% capacity in freezing temperatures
• Warm up phone before turning on in extreme cold

Airplane mode savings:

• Turn on airplane mode when not actively using phone
• Enable WiFi/data only when needed
• Saves 60-70% battery life
• Phone still works for photos, offline maps, entertainment

Battery-saving settings:

• Reduce screen brightness to 30-40%
• Enable auto-brightness (adapts to conditions)
• Turn off background app refresh
• Disable location services except for maps
• Close unused apps
• Enable low power mode at 50% battery (not just 20%)

Photo Management

Shooting strategy:

• Take photos (doesn't use data)
• Review and delete bad shots each evening
• Keep 20-30 best photos per day
• Delete duplicates and blurry shots

Uploading strategy:

• Compress photos before uploading (apps like Photo Compress)
• Upload in batches when signal is strong (Namche, Tengboche)
• Don't try uploading at high altitude (painfully slow, wastes data)
• Consider posting retrospectively after trek (saves data, more curated)

Cloud backup:

• Enable Google Photos or iCloud backup on WiFi only (not mobile data)
• Backup photos at hotel WiFi in Kathmandu before/after trek
• Don't waste mobile data on automatic backups

Communication Efficiency

Message batching:

• Instead of sending 20 messages throughout day, send 2-3 batch updates
• Write messages offline, send when signal available
• Reduces time spent with phone, improves battery life

Voice messages vs typing:

• In Viber/Telegram, voice messages are more efficient than typing on trail
• Easier to record 30-second voice message than type paragraph with cold fingers
• Uses similar data (30-second voice = 250KB, text message = 1KB)

Preset messages:

• Create message templates for common updates:
  • "Made it to [village], all good, weather great, trekking going well"
  • "At [altitude], feeling strong, photos uploading"
  • "Taking rest day at [location] for acclimatization"

WiFi Optimization

When to buy WiFi:

• ❌ Don't buy at lower altitudes (use mobile data)
• ❌ Don't buy at locations with good 4G (waste of money)
• ✅ Buy at high altitude dead zones (Lobuche, Gorak Shep if no mobile signal)
• ✅ Buy if sharing cost among 3-4 trekkers
• ✅ Buy on rest days when you have time to use it

Maximizing WiFi value:

• Use off-peak hours (early morning, mid-afternoon)
• Compress all content before uploading
• Focus on essential communication first
• Entertainment last (music streaming, social media browsing)

Frequently Asked Questions

General Questions

1. Can I use my home country phone in Nepal?

Yes, if your phone is unlocked. Most modern smartphones work in Nepal. Ensure your phone is carrier-unlocked before traveling. If locked, contact your carrier to unlock it (usually free after contract obligation period).

2. Do I need both Ncell and Nepal Telecom SIM cards?

For standard EBC or ABC treks, one SIM is sufficient (Ncell for Everest, NTC for Annapurna). However, buying both ($1.60 total) provides redundancy and costs almost nothing. Experienced trekkers carry both for maximum coverage flexibility.

3. Can I keep my home SIM card in my phone?

Yes, most modern phones support dual-SIM (physical + eSIM, or 2 physical). Keep home SIM for banking 2FA and important notifications, use Nepal SIM for data and local calls. Disable data roaming on home SIM to avoid charges.

4. How much data do I really need for a 2-week trek?

Light usage: 10-15GB (messaging, occasional photos)
Moderate usage: 20-30GB (daily updates, regular photos, some video calls)
Heavy usage: 40-60GB (frequent video calls, social media, music streaming)

Most trekkers fall in the 20-30GB range. A 30GB package for 28 days costs ₨800 ($5.80)—excellent value.

5. Is WiFi available at Everest Base Camp?

Yes, tea houses at Gorak Shep (last village before EBC) offer WiFi, but it's slow, expensive (₨1,000-1,500/day), and unreliable. Ncell mobile data works intermittently at Gorak Shep and occasionally at EBC itself. Don't rely on connectivity at EBC.

SIM Card Questions

6. Where exactly at the airport do I buy SIM cards?

After collecting baggage and passing through customs, exit into the arrivals hall. Turn right immediately—you'll see Ncell and Nepal Telecom counters with clear signage. Can't miss them.

7. What if I arrive at night when counters are closed?

If arriving after 5:30 PM, counters are closed. Options: (1) Purchase SIM next morning in Thamel, (2) Ask your hotel to arrange SIM purchase, or (3) Wait until the following day. Most trekkers spend 1-2 days in Kathmandu, so missing airport counters isn't critical.

8. Can I buy a SIM card without a passport photo?

Some locations (especially Thamel) have instant photo printing for ₨100-200. However, it's easier to bring 2 passport photos from home. Many trekkers need photos for permits anyway.

9. How long does SIM card activation take?

10-15 minutes typically. Occasionally up to 2-4 hours if system delays. In rare cases, can take 24 hours. If not active after 24 hours, return to point of purchase.

10. Can I recharge my SIM card on the trail?

Yes, most tea houses sell recharge scratch cards (₨100, ₨500, ₨1,000 denominations). Prices are marked up 10-20% above Kathmandu rates. Tea house staff can help apply recharge.

Coverage Questions

11. Will I have signal at Everest Base Camp?

Intermittently. Ncell provides weak 3G signal at EBC (5,364m) that comes and goes. You might be able to send text messages or make brief calls, but don't rely on it. Signal is better at Gorak Shep village (5,164m).

12. What about Annapurna Base Camp coverage?

NTC provides weak but generally functional 3G at ABC (4,130m). Calls and messages work most of the time. Data is slow but usable. Ncell doesn't work at ABC—must have NTC.

13. Are there complete dead zones with no coverage?

Yes. Examples:

• Thorong La Pass (5,416m) on Annapurna Circuit: minimal to no coverage
• High camps on Manaslu Circuit (4,400m+): no coverage for 3-4 days
• Remote regions (Dolpo, Makalu, Upper Kanchenjunga): extremely limited

Standard EBC and ABC routes have 60-70% coverage overall.

14. Does weather affect mobile signal?

Yes, significantly at high altitude. Heavy clouds, precipitation, and storms degrade signal quality. Sunny days have better signal than cloudy days. This is why solar-powered towers sometimes don't work after several cloudy days.

15. Which provider is best for Langtang?

Nepal Telecom (NTC) is essential. Works to Kyanjin Gompa (3,870m) with surprising reliability. Ncell is largely useless above Lama Hotel (2,480m).

Cost Questions

16. What's the total cost for connectivity on a 2-week trek?

Minimal setup: $8-12 (one SIM, 15-20GB data, no WiFi)
Standard setup: $18-30 (dual SIM, 30-40GB data, occasional WiFi)
Premium setup: $35-50 (dual SIM, high data, frequent WiFi)

Most trekkers spend $20-30 total for excellent connectivity.

17. Is it cheaper to use eSIM or physical SIM?

Physical SIM is 5-10x cheaper. eSIM (Airalo/Holafly) costs $26-66 for similar usage that costs $5-10 with physical Ncell/NTC SIM. eSIM trades money for 15 minutes of convenience.

18. How much does it cost to charge my phone at tea houses?

Lower altitudes (2,000-3,000m): ₨200-400 ($1.50-$3)
Mid altitudes (3,000-4,000m): ₨400-600 ($3-$4.50)
High altitudes (4,000m+): ₨600-1,000 ($4.50-$7.25)

Bring a 20,000mAh power bank to avoid high-altitude charging fees.

19. Are data packages refundable if I don't use all the data?

No, prepaid data packages are non-refundable. Unused data expires at end of validity period. Buy appropriate package size for your needs.

20. Do I get charged for receiving calls?

No, incoming calls are free on Ncell and NTC. You only pay for outgoing calls and messages.

Technical Questions

21. What phone network bands does Nepal use?

2G: 900/1800 MHz
3G: 2100 MHz (WCDMA)
4G LTE: Band 3 (1800 MHz), Band 5 (850 MHz)

All modern smartphones are compatible (iPhone, Samsung, Google Pixel, OnePlus, etc.).

22. Can I use my phone as a WiFi hotspot?

Yes, you can share your mobile data via personal hotspot. Useful for sharing one data package among trekking partners. However, drains battery quickly—bring power bank.

23. Will my phone work in cold temperatures?

Phones work, but battery life decreases significantly in freezing temperatures. Keep phone inside jacket pocket for warmth. Don't leave phone in cold tent overnight. If phone shuts off from cold, warm it up gradually before turning on.

24. Can I use Google Maps offline?

Yes. Download offline maps of Nepal (specifically Khumbu and Annapurna regions) before trekking. Maps.me is also excellent—fully offline, hiking trail details, tea house locations.

25. What's the best way to backup photos during trek?

Option 1: Upload to Google Photos/iCloud when you have strong WiFi (Kathmandu, Namche Bazaar)
Option 2: Bring small USB drive, copy photos from phone each evening
Option 3: Email yourself small batches of best photos

Don't rely on trail connectivity for photo backup—do it in Kathmandu before/after trek.

Emergency Communication Questions

26. How do I call for helicopter rescue?

Step 1: Contact your trekking guide first (they coordinate rescue)
Step 2: Call your travel insurance emergency hotline (they authorize evacuation)
Step 3: If above fail, call helicopter company directly (Simrik Air +977-1-4499933)

Guides have satellite phones for emergencies. Most rescues are coordinated by guides and insurance companies.

27. What if I have no mobile signal and need help?

Immediate danger: Send message with descending trekkers to call rescue when they reach signal
Medical emergency: Trekking guide has satellite phone
Tea house emergency: High-altitude tea houses may have satellite phone
Non-urgent: Descend to lower altitude with mobile coverage

True emergencies on standard routes are rare—help is almost always available through guides or tea houses.

28. Does Viber work for emergency calls?

Viber calls use internet data—requires 3G/4G signal. In true emergencies, regular phone calls are more reliable (work on 2G, weaker signal). Save Viber for non-emergencies.

29. Should I bring a satellite phone?

No, unless you're doing extremely remote trek (Dolpo, Makalu). For standard EBC/ABC treks, guides have satellite phones, mobile coverage is decent, and tea houses have communication options. Sat phone rental ($10-15/day + usage) isn't worth it for most trekkers.

30. What if my phone dies and I'm lost?

This is why paper maps are still important. Download offline maps before trek, but always carry paper map as backup. If both fail, stay on main trail, ask other trekkers for directions, or wait for trekking parties you can follow.

App and Service Questions

31. Does WhatsApp work in Nepal in 2026?

No, WhatsApp is blocked in Nepal as of 2025. Use Viber instead—it's the most popular messaging app in Nepal and fully functional.

32. Can I video call my family from Nepal?

Yes, when you have good 4G signal (Kathmandu, Pokhara, Namche Bazaar, lower trekking villages). Video calls use 4-8 MB per minute—requires strong signal and decent data package. Expect video calls to be pixelated or laggy above 4,000m.

33. Does Spotify/Apple Music work on Nepal mobile data?

Yes, but streaming music consumes significant data (40-100 MB per hour). Download playlists for offline listening before trek. Don't waste mobile data streaming music—save it for communication.

34. Can I use Google Translate offline?

Yes, download Nepali language pack for offline use before trek. However, English is widely spoken in tourist areas and trekking routes. Guides, tea house owners, and shopkeepers in Lukla/Namche/Pokhara speak excellent English.

35. What about banking and mobile payment apps?

Nepal is largely cash-based, especially on trekking routes. Mobile payment apps like eSewa and Khalti exist but aren't useful for trekkers. Bring Nepali rupees in cash. Some trekking agencies accept credit cards in Kathmandu, but trails are cash-only.

eSIM Questions

36. Is eSIM better than physical SIM for Nepal?

No, for trekkers. eSIM costs 5-10x more ($26-66 vs $5-10) for equivalent usage. eSIM is data-only (can't make regular phone calls). Physical SIM provides better value, flexibility, and full calling capability. eSIM only makes sense for very short city-based trips.

37. Can I buy eSIM after arriving in Nepal?

eSIMs (Airalo, Holafly) must be purchased online before arrival. Ncell and NTC offer eSIM conversion but requires in-person registration at their offices—defeats the convenience purpose.

38. Does eSIM work better in the mountains?

No, eSIM uses same networks as physical SIM (Ncell or NTC). Coverage quality is identical. No advantage to eSIM for trekking connectivity.

WiFi Questions

39. Is tea house WiFi fast enough for video calls?

At lower altitudes (Lukla, Phakding, Namche), sometimes yes. Above 4,000m, absolutely not. WiFi at high altitude (Dingboche, Lobuche, Gorak Shep, ABC) is painfully slow—barely adequate for text messaging. Video calls require mobile 4G data.

40. Can I share one WiFi card among multiple people?

Technically possible (one person buys card, shares via hotspot), but incredibly slow. Tea house WiFi is already a single mobile connection divided among guests—further dividing among your group makes it nearly unusable. Better for each person to use their mobile data.

41. Why is WiFi so expensive at high altitude?

Infrastructure costs. Tea houses at 4,500m+ are:

• Powered entirely by solar (expensive, limited)
• Supplied by porters carrying equipment (costs money)
• Using expensive satellite/mobile backhaul
• Located in remote areas with no grid power

₨800-1,200 ($6-9/day) reflects real costs, not exploitation.

42. Should I just skip WiFi entirely and use mobile data?

Yes, for most trekkers. Mobile data packages provide better value, faster speeds, and more flexibility. Only buy WiFi where mobile signal doesn't exist.

• ❌ Satellite phone rental: Guides have sat phones, mobile coverage adequate on standard routes
• ❌ Extensive WiFi purchases: Mobile data is better value and more reliable
• ❌ International roaming on home SIM: Extremely expensive, unnecessary with local SIM
• ❌ VPN service (for most): Blocked apps (WhatsApp/Facebook) aren't essential, Viber works fine

The Smart Trekker's Connectivity Checklist

Before leaving home:

• ☑ Phone unlocked (not carrier-locked)
• ☑ Viber downloaded and tested
• ☑ Offline maps downloaded (Maps.me, Google Maps)
• ☑ Emergency numbers saved
• ☑ Travel insurance emergency hotline programmed in phone
• ☑ 2 passport photos for SIM registration

At Kathmandu airport:

• ☑ Buy Ncell (for Everest) or NTC (for Annapurna) SIM card
• ☑ Purchase 20-30GB data package immediately
• ☑ Test SIM before leaving airport
• ☑ Consider buying second SIM for redundancy

Before starting trek:

• ☑ Fully charge phone and power bank

Conclusion: Staying Connected Responsibly

Nepal's connectivity infrastructure has improved dramatically, providing trekkers with reliable communication options that were unimaginable just 10 years ago. You can now video call family from Namche Bazaar (3,440m), upload summit photos from near Everest Base Camp, and navigate with GPS throughout your trek.

However, the best Nepal trekking experiences still involve balance. Constant connectivity can diminish the profound experience of being present in the mountains, disconnected from the digital noise of daily life. Many trekkers report that their most meaningful moments came during signal-less stretches where they were fully present—conversation with fellow trekkers, sunrise without Instagram, tea house camaraderie without email.

The healthy approach:

1. Set up proper connectivity (costs $15-30, takes 20 minutes)
2. Use it purposefully (morning check-ins, evening updates)
3. Embrace offline periods (put phone away during hiking, be present)
4. Enjoy the digital detox (fewer screens, more mountain views)

With the information in this guide—from choosing the right SIM card and understanding coverage maps to emergency communication and cost optimization—you're equipped to stay appropriately connected while still experiencing the transformative power of Nepal's mountains.

The mountains have been here for millions of years. Your emails can wait a few days.

Safe travels, and may your connectivity be strong and your experience unforgettable.
