Staying connected in Nepal is more achievable than most travelers expect — right up until it isn’t. Kathmandu has decent 4G coverage and hotel WiFi that can handle a video call without drama. Pokhara’s lakeside has good connectivity. Then you take the flight to Lukla, walk uphill for a week, and somewhere above 4,500m you realize you haven’t had a signal in two days and the phone has 8% battery because the teahouse charges NPR 400 per charge. Planning for all of this — the good connectivity and the none at all — is what this guide is for.
Electricity in Nepal: Voltage, Plug Types, and Reliability
Voltage and Frequency
Nepal runs on 230V, 50Hz — the same standard used across most of Europe, South Asia, and Australia. If your device is dual-voltage (100–240V, which most modern laptops, phone chargers, and cameras are — check the label on the charger brick), you don’t need a voltage converter, only a plug adapter. If you’re traveling from the US or Canada with older electronics, check the voltage rating before plugging in. Running a 110V-only device on 230V will damage it.
Plug Types
Nepal officially uses three socket types, and you’ll encounter all of them:
- Type C — two round pins, the standard European plug. The most common socket in newer buildings and tourist-facing guesthouses. Most European travelers need no adapter at all.
- Type D — three large round pins in a triangular arrangement, the old Indian standard. Still common in older buildings and some rural areas.
- Type M — three large round pins (South African style), larger version of Type D. Less common but present in some buildings.
The practical solution is a universal travel adapter that covers multiple pin configurations. A good universal adapter costs $10–15 USD and is available at Thamel gear shops or Kathmandu electronics stores (Bagh Bazaar area) for NPR 500–1,000. Many Thamel guesthouses have Type C and Type D sockets in rooms — UK travelers (Type G) and US/Canadian travelers (Type A/B) will need an adapter from day one.
Electricity Reliability in Kathmandu
This is where Nepal’s recent infrastructure story is genuinely worth knowing. From roughly 2008 to 2016, Kathmandu experienced severe scheduled power cuts called load shedding — at the worst point in 2012–13, the city was without power for 16–18 hours per day. Hotels and businesses ran on generators; the entire city operated around an unpredictable power schedule that made normal life genuinely difficult.
That has changed significantly. Nepal brought new hydropower capacity online — particularly the 456MW Upper Tamakoshi project and earlier expansions — and by 2017–18 load shedding in Kathmandu was largely eliminated. The situation now is much closer to normal urban power: occasional unscheduled outages (especially during monsoon when demand peaks), reliable power in most hotels and guesthouses during the day and night, and UPS backup systems in most places that maintain power for a few hours when outages occur.
For travelers: don’t build your plans around 2015-era advice about Nepal’s power situation. The power is mostly on. Occasional outages happen — usually 30 minutes to a few hours — and hotels handle them with UPS or generator backup. Rural areas and smaller towns still have less reliable supply.
Buying a SIM Card in Nepal
At Tribhuvan Airport
The easiest place to buy a Nepali SIM is in the arrivals hall at Tribhuvan International Airport. Both Ncell and Nepal Telecom (NTC) have booths that are staffed for international flight arrivals, including late-night flights. The process takes 10–20 minutes:
- Choose a provider (Ncell or NTC — more on this below)
- Hand over your passport for copying or show it for registration
- Pay for the SIM and a data package in cash (NPR preferred; some booths accept USD)
- The SIM is registered and activated while you wait
- The staff will usually install it and confirm it’s working before you leave
SIM card cost: NPR 100 for either provider. This is just the SIM — data packages are purchased separately.
If you miss the airport booths or arrive on a domestic connection, Thamel has SIM shops on almost every block. The same registration process applies; bring your passport. Some shops will also set up the data package for you and confirm connectivity before you leave.
Ncell vs. Nepal Telecom: Which to Choose
Ncell (operated by Axiata, a Malaysian telecoms group) is the private-sector carrier and generally has better 4G coverage in tourist areas and more consistent data performance. In Kathmandu, Pokhara, and the main trekking approach towns, Ncell’s 4G is reliable and reasonably fast. Their app and online top-up systems are more user-friendly than NTC’s. Most independent travelers and budget guesthouse owners use Ncell.
Nepal Telecom (NTC) is the government carrier and has broader coverage in remote areas — some sections of the country where Ncell has no signal still have NTC coverage. Their CDMA network historically covered areas that standard GSM/LTE doesn’t reach. For trekkers going to genuinely remote western or eastern Nepal (Dolpo, Kanchenjunga, far west Terai), NTC can be the better choice. For standard EBC/Annapurna routes, Ncell is fine.
You can buy both SIMs and alternate. Each costs NPR 100 and phone numbers are cheap — some travelers carry both for longer trips in remote areas.
Data Packages and Costs
Both Ncell and NTC update their data package offerings regularly, so specific package names change. These are the approximate pricing tiers as of 2024–25:
Ncell Data Packages (Approximate)
- Daily packages: NPR 25–60 for 100MB–1GB valid 24 hours — useful for a single connected day in Kathmandu
- Weekly packages: NPR 100–200 for 1–3GB valid 7 days
- Monthly packages: NPR 350–700 for 5–20GB valid 28–30 days — the best value for a standard 2–3 week Nepal trip
- Unlimited/high-volume: NPR 800–1,500 for “unlimited” or high-data monthly packages with speed throttling after a threshold
For a standard 3–4 week Nepal trip that includes time in Kathmandu, Pokhara, and trekking: a monthly 10–15GB package for NPR 450–600 is the practical choice. You’ll use most of the data in the cities and at Namche; the rest of the trek you’re largely offline regardless of how much data you have.
Top-up and package purchases can be done via the Ncell app, USSD codes (*17123# for balance check), or at any of the thousands of shops in Kathmandu and Pokhara that display Ncell signage. Buy a package in Kathmandu before heading to the mountains — adding data from a lodge above Namche is possible in theory and unreliable in practice.
Nepal Telecom Data Packages
NTC packages are priced comparably to Ncell — NPR 100–700 depending on duration and volume. Their monthly packages are slightly more competitive for voice calls (NTC to NTC rates are very cheap). For data specifically, Ncell edges ahead in most tourist areas on speed and consistency.
eSIM Options for Nepal
eSIM providers have expanded into Nepal coverage over the past few years and are worth considering for travelers with compatible unlocked phones who want connectivity without the SIM-swapping process.
Providers like Airalo, Holafly, and Nomad offer Nepal eSIM packages. Coverage runs through Ncell or NTC networks. Typical pricing:
- 1GB / 7 days: approximately $5–8 USD
- 5GB / 30 days: approximately $12–20 USD
- 10–15GB / 30 days: approximately $20–35 USD
The eSIM premium over a local SIM is real but not outrageous for shorter trips. The convenience — activated before you leave home, no airport queue, no physical SIM handling — is genuine. For a 10-day Kathmandu-and-Pokhara trip without trekking, an eSIM from Airalo is a perfectly sensible choice. For a 3-week trip including trekking where data needs are higher, a local Ncell SIM is cheaper and refill logistics are easier.
To use an eSIM, your phone must support eSIM, be unlocked from your home carrier, and have the eSIM profile installed before you arrive. Check compatibility before purchasing — most recent iPhones (XS and later), Pixel phones (3 and later), and Samsung Galaxy S series support eSIM.
Internet on the Trek
Connectivity on the EBC Route
Ncell has made significant infrastructure investments in the Khumbu region and signal exists in surprising places — patchy coverage in some sections between Lukla and Namche, and reasonable 3G/4G in Namche Bazaar itself. Above Namche, coverage becomes increasingly unreliable. Dingboche (4,410m) has occasional signal on Ncell. Above Dingboche, you’re effectively offline on mobile data.
Teahouse WiFi on the EBC route runs on satellite VSAT connections and is available from Lukla upward in most lodges, at NPR 200–500 per day pass. Quality degrades with altitude:
- Lukla to Namche: Usable for messaging, email, basic browsing. Video calls possible in off-peak hours.
- Namche Bazaar: Best connection on the route. Nepal Telecom has a dedicated installation. Social media, WhatsApp calls, and light browsing work reasonably well.
- Tengboche to Dingboche: Inconsistent. Some lodges have workable connections; others drop every few minutes. Plan for unreliable.
- Lobuche to Gorak Shep: Expensive satellite WiFi at some lodges (NPR 500–1,000/day), frequently slow or unavailable. Most experienced trekkers accept being offline from here.
Connectivity on the Annapurna Circuit
Coverage on the Annapurna Circuit is broadly similar — good in Pokhara, workable in lower villages, increasingly patchy above 3,000m. Manang (3,519m) has satellite WiFi at most lodges and reasonable Ncell signal for basic data. Above Manang on the Thorong La approach, signal fades. Muktinath (3,760m) on the other side of the pass has connectivity, as the road connection from Jomsom brings better infrastructure.
Power Banks: Essential Equipment
A power bank is not optional gear for Nepal trekking — it’s infrastructure. The combination of cold temperatures (which reduce lithium battery efficiency), charging costs at teahouses, and long days between reliable power access means that managing your device battery is an active logistics task from Namche upward.
Recommended capacity: 20,000mAh minimum. This charges most smartphones 4–5 times from empty and handles a camera battery or two as well. A 20,000mAh power bank at full charge in Kathmandu can cover 3–4 days above Namche without needing a teahouse charge — long enough to get to an acclimatization day at Dingboche where the charging cost is slightly lower.
Airline restrictions: power banks up to 100Wh (approximately 27,000mAh at 3.7V) are permitted in carry-on luggage; above 100Wh requires airline approval; above 160Wh is generally prohibited from passenger aircraft entirely. A standard 20,000mAh bank is around 74Wh — well within carry-on limits and typically well within carry-on allowance on Nepal domestic flights too.
In cold conditions above 4,000m, keep the power bank in an inside pocket of your jacket during the day. Lithium cells lose capacity rapidly below 0°C — a bank that shows 60% charge at room temperature may behave as if nearly empty in the cold. Warming it restores the capacity.
Charging Costs at Teahouses
Teahouses charge for electricity because generating power at altitude — via solar panels, battery storage, and diesel generators as backup — is genuinely expensive. Standard charging fees:
- Lukla to Namche: Often free, or NPR 50–100 per device per charge
- Namche to Tengboche: NPR 100–300 per device
- Dingboche to Lobuche: NPR 200–500 per device
- Gorak Shep: NPR 300–600 per device — some lodges run purely on limited solar
Charging happens in the dining room, not in your room in most cases. Plug in when you arrive and eat dinner, check at dessert, and unplug before another trekker needs the outlet. The dining room outlet situation can get competitive in October.
Staying Connected While Trekking: Practical Preparation
The things that make the offline sections of a Nepal trek manageable with minimal stress:
Download offline maps before leaving Kathmandu. Maps.me covers the Nepal trails well with offline functionality. Google Maps offline areas work for approach roads and city navigation. The trails themselves are often better represented in Maps.me or Gaia GPS. Download your entire route while you have WiFi — don’t plan to do it from Namche.
Download entertainment for the long trail days and evenings. Spotify offline playlists, Netflix downloads for evenings in teahouses, podcasts, audiobooks. The trail days are long and teahouse evenings after dinner are longer. The period after 7 PM in a Dingboche lodge with no WiFi and no signal is when people who prepared have a good evening and people who didn’t stare at a wall.
Tell people at home what to expect. A useful message before you go: “Signal will drop after [date] and I’ll be contactable again from [date] when I get back to Namche. If there’s a genuine emergency, contact [trekking agency or guide’s number].” This prevents family worry spirals over three days of silence.
WhatsApp and Facebook Messenger for communications. When you do hit WiFi on the trail, these apps work better than standard SMS internationally. Voice messages work even on slow connections when voice calls won’t.
A Note from Nepal Trail Guide
The offline stretch of a Nepal trek — roughly from above Dingboche on EBC, above Manang on Annapurna, and the equivalent on other routes — is one of the underrated experiences of the whole trip. Most people who do it expecting to hate the disconnection find that by day three they’ve stopped reaching for their phone automatically, and by day five the absence of it feels genuinely restorative. The mountains are a legitimate reason to be unreachable.
Get the SIM at the airport, buy a sensible data package, carry a 20,000mAh power bank, download your maps and your playlists, and then accept that above a certain altitude Nepal is still Nepal: dramatic, physical, and entirely indifferent to your notification settings.
