SIM cards and wifi in Nepal for trekkers

A local SIM card gives you a Nepali number and mobile data in Kathmandu, Pokhara and most towns, and lodge wifi fills some gaps in the villages, but neither is reliable on the trail, and the right plan is to treat a signal as a bonus and to arrange communication so it works without one. Two operators, Ncell and Nepal Telecom, are the best known, and coverage differs by route. We do not quote SIM or data prices because they are not in our cost tables and operators change them often; the method below tells you how to ask. The route facts come from our pages, verified 19 October 2026.

Do you need a SIM at all

For most trekkers a local SIM is useful but not essential. It is worth it if you want to:

• Call or message a guide, driver, hotel or partner with a local number.
• Use maps, translation and messaging in cities and towns.
• Get data for a few days in villages with a signal.

It is less valuable if you will be on a remote route for most of the trip, if your phone is locked to a carrier or if you have a plan that roams cheaply. Be aware that the SIM is for convenience, not safety.

Buying a SIM: what to ask

1. Which operator? Ncell and Nepal Telecom are the two best-known. Ask which has the better signal on your route; your guide or agency will know.
2. What documents are needed? Bring your passport; the seller will tell you what else is required, and rules can change, so follow what the shop says and keep the receipt.
3. What does the package include? Ask about data, validity and whether it can be topped up in a village.
4. Is your phone unlocked? A locked phone will not accept a local SIM.
5. Does it work on your phone? Test it in the shop before you leave.

Buy from an official shop or a reputable counter, not from a street seller, and avoid giving more personal data than needed. The wall in the first photo, at Nayapul, carries an Ncell advertisement, a reminder that these operators are visible even at trailheads, but a sign is not a signal.

Why trail coverage is patchy

The Himalaya is steep, with deep valleys, and mobile masts are placed where they serve villages, not trails. On most routes you will have signal in some villages and none on the walks between them, and conditions change with weather, power and maintenance. We found no source that gives reliable route-by-route coverage, so we do not publish a coverage table. Ask your guide, your lodge owner and other trekkers coming down, and treat a bar of signal as luck.

Lodge wifi

Many teahouses sell wifi by prepaid card or by the hour, and it is typically slow and often absent at the highest villages. It works for a short message, not for video calls or uploads. Power is also limited: lodges run on solar or small generators, so charging costs money and wifi can drop when the batteries are low. Our teahouse prices guide and extras guide explain the pattern.

A communication plan that works without a signal

1. Tell someone at home your itinerary and the dates you expect to be out of contact. Agree a latest check-in time and what they should do if you miss it.
2. Share your plan with your partner and guide: who calls whom, and who has the insurer's number.
3. Carry the insurer's 24-hour number and policy number on paper and on your phone; see the trekking insurance guide.
4. Download maps and documents before you leave the city.
5. Know the clinics. The Himalayan Rescue Association runs clinics in some high villages; see the HRA clinics guide.
6. Do not rely on a phone for an emergency. Your guide, the lodge and other trekkers are the first help.

Our guide to trekking partner safety roles, signals and emergency plans explains what to agree with the people you walk with.

Saving battery

Cold and screens drain batteries. Use airplane mode on the trail, lower the brightness, switch off background updates and keep the phone inside your jacket or sleeping bag at night. A power bank is the cheapest insurance; check the packing list for adapters.

By region

On the Everest Base Camp route, the lower villages are the best places for signal and wifi, and the higher villages are patchy. On Poon Hill, a short trek in the Annapurna foothills, signal is more likely in the villages but still not guaranteed. These are general patterns, not guarantees. If you trek in a restricted area, such as Manaslu or Upper Mustang, your agency and guide manage communication; ask in advance how.

Sharing with partners

If you travel with a partner found through our trekking partner hub, agree how you will stay in touch before you start, and who has a SIM. Contact details stay hidden until both of you agree, so share a number only when you are ready. Our what to agree guide covers the rest.

Three trekker types and what suits each

The short-trek visitor. If you are doing a few days from Pokhara or Kathmandu, a local SIM is mainly for convenience: calling a driver, messaging a guide and using maps in town. Buy it in the city on your first day, test it in the shop and expect patchy signal on the trail. For a trek this short, lodge wifi and a power bank may be all you need.

The long-trek trekker. If you are away for two or three weeks on a major route, a local SIM gives you a number your guide and agency can reach, and data in villages that have it. Plan for long gaps in signal, and agree check-in days with home rather than daily messages. Carry paper copies of your insurance details and itinerary.

The restricted-area trekker. On routes such as Manaslu or Upper Mustang your agency and guide manage communication, and signal can be absent for days. Ask the agency how it will reach you and how you can reach it, and give your family the agency's contact rather than only your own.

An emergency contact card

Whatever you buy, write a small card and keep it in your daypack and in a plastic bag. It should list your name, nationality and passport number, your insurer's name, policy number and 24-hour assistance number, your agency's phone number, your guide's name and number, and one contact at home. Add any medical condition and allergy. Take a photo of the card on your phone as well, but remember that a dead battery cannot show it. Share a copy with your partner. Our trekking insurance guide explains what to check in the policy, and our partner safety guide explains how to agree an emergency plan.

Offline tools worth setting up before you leave

Download offline maps of the region and the cities you will pass through, a translation pack for Nepali if your phone supports it, your tickets and permits as saved files and your messaging history for key contacts. Turn off automatic app updates and cloud backups while you are on the trail, because they quietly use data and battery when a signal appears. Set a screen lock, since your phone holds documents and photos of your passport.

Privacy and safety when sharing a number

Be careful with whom you share your local number, especially with people you have met online. On our platform, contact details stay hidden until both trekkers agree, and we suggest you meet in a public place before you swap numbers. A local SIM number is easy to change, but your home number is not, so decide which to share. See our guide to how to find a trekking partner safely.

Charging, power banks and cold

The most useful accessory is a power bank, but cold reduces battery capacity, and so does leaving it in your pack at night. Keep it in your sleeping bag overnight with your phone. If you rely on lodge charging, note that power is limited and that charging is billed; our extras guide explains how, and the packing list covers adapters and cables.

More guides are in the transport and logistics hub. Operators and rules change; confirm SIM terms in the shop and permit rules with the Nepal Tourism Board.
