SIM cards in Nepal — the complete guide

For most visitors on a normal itinerary — Kathmandu, Pokhara, Chitwan, Lumbini, the main highways — Ncell gives the better everyday data experience in towns and is the easier tourist purchase, because Ncell sells a dedicated tourist plan designed to be bought with nothing but a passport.

For anyone going above the treeline, into remote hills, or to far-western districts, Nepal Telecom is the one to have. As the state operator it carries a universal-service obligation, and its network reaches villages and trekking valleys that no commercial operator would build for. Trekkers routinely carry NTC for coverage and Ncell for speed.

If you will be in Nepal for more than a couple of weeks and rely on being reachable, buying both is genuinely sensible and legal — foreign visitors are generally allowed up to two SIMs across operators. Two prepaid SIMs cost less than a single day's hotel room.

Nepal does not sell unregistered SIMs. The shop takes your original ID, photographs or photocopies it, fills a registration form with your details, and in most cases takes your signature and thumbprints. The number is then tied to you personally in the operator's KYC record.

This has three practical consequences. First, you cannot buy a Nepali SIM before you arrive — you have to be physically present with your document. Second, a SIM handed to you by a friend, landlord or employer is legally still their number, which matters for banking, eSewa and anything that sends an OTP. Third, if you lose the phone, only the registered owner can block and replace the number.

If you are in that second situation — using a number registered to somebody else — fix it. There is a formal ownership-transfer process, and it is covered in its own guide below.

Requirements vary by who you are, which is why the three audience guides exist. In outline:

A plain Nepali prepaid starter SIM is very cheap — Nepal Telecom's prepaid SIM has been sold at around Rs 90, which includes a small amount of starting balance and a token data and voice allowance. That is the SIM itself; you then buy a data pack on top.

Tourist plans are priced differently, as bundles. Ncell's TouristPro range has been sold at Rs 595 for 7 days, Rs 995 for 14 days and Rs 1,995 for 28 days, each with unlimited data and calls under a fair-usage policy — the 7-day pack throttles after 10 GB and the 14-day pack after 25 GB. Those plans are sold only to non-Nepali citizens.

As a rough planning figure, a fortnight of comfortable data use in Nepal costs somewhere between Rs 600 and Rs 2,000 — under US$15 either way. Data in Nepal is cheap by international standards; the expensive mistake is arriving with international roaming switched on.

Tribhuvan International Airport in Kathmandu has NTC and Ncell counters in the arrivals hall past immigration, and they open for most international arrivals including late-night ones. Buying there is the fastest option and the staff handle foreign registration all day long.

In town, operator-owned centres (Ncell Centres, NTC offices) can do everything including ownership transfers and replacements. Small shops and mobile-repair stalls sell SIMs and recharge everywhere, but they can only do a straightforward new registration — for anything unusual you need an operator centre.

One practical note from repeated visitor reports rather than any published rule: airport counters occasionally push the most expensive tourist bundle. Ask what the cheapest pack that covers your dates is, and check whether a normal prepaid SIM plus a data pack is cheaper for your trip length.

Nepal's mobile coverage is far better than most visitors expect. 4G reaches all 77 district headquarters and most of the accessible hills; both major operators have live 4G, and there is meaningful coverage along the main trekking corridors including much of the Everest and Annapurna routes.

What changes in the mountains is not whether there is signal, but where. Signal in a Himalayan valley is line-of-sight to a tower on a ridge, so you get bars at a pass or a viewpoint and nothing in the valley floor twenty minutes later. Plan on messaging when you reach a lodge on a spur, not on being continuously reachable.

Above roughly 4,000 m, and in the deep gorges of Manaslu, Dolpo and Upper Mustang, expect long dead stretches on any network. Groups going into genuinely remote terrain carry a satellite messenger, not a better SIM.

The step-by-step process, the documents and the pitfalls are meaningfully different for each of these three readers, so each has its own guide rather than one page hedging between them.
