Yes, physical tourist SIM cards are sold in Nepal, and passport registration is required to activate one.
In detail
Tourist SIM available ▾
Yes — Nepal is a straightforward market for physical tourist SIMs, and Ncell in particular sells a dedicated Tourist SIM product to non-Nepalese visitors. Ncell's tourist plans run 7, 14 or 28 days, are explicitly restricted to non-Nepalese citizens, and are sold at Tribhuvan International Airport (TIA) in Kathmandu, at Ncell Centres in major cities, and through authorised retailers nationwide — both a physical tourist SIM and a tourist eSIM are offered. Nepal Telecom (NTC, branded Namaste) also sells physical prepaid SIMs to tourists, with its own counter at TIA; recent traveller reports describe Ncell and Nepal Telecom counters side by side in the arrivals area. This makes Nepal notably more tourist-friendly on the physical-SIM side than India, since Ncell has built a dedicated tourist product distributed through both the airport and the normal retail network, rather than a generic multi-operator counter with no purpose-built tourist plan.
SIM registration required ▾
Yes. Nepal requires identity registration for any physical SIM, including tourist SIMs. Nepal's telecom regulator requires the subscriber to be physically present with an original ID checked against a copy, and a passport is explicitly accepted for foreign visitors. Ncell's Tourist SIM specifically requires the original passport for registration and activation, and its general new-SIM process also asks for a passport photocopy and a recent passport-size photo. Nepal Telecom's subscriber terms similarly require a copy of the passport/ID and a photograph. There's no Aadhaar-style national-ID requirement for foreigners — the passport alone satisfies the telecom KYC process. Separately, Nepal also runs an MDMS handset-registration system for imported devices, which registers the phone itself rather than the SIM subscriber and is a distinct process from SIM registration.
Airport SIM counter ▾
Yes. Ncell's official Tourist SIM page confirms sales at TIA, and its store locator specifically lists an Ncell Centre inside the airport's arrival terminal offering new-SIM service. Tribhuvan International Airport's own floor-information page separately lists a Nepal Telecommunication Corporation (Nepal Telecom / NTC) counter on the ground floor, and recent traveller reports describe the Ncell and Nepal Telecom counters as side by side in the arrivals area. For a foreign tourist specifically, Ncell is the cleaner confirmed option since it has a purpose-built Tourist SIM product explicitly sold at TIA, rather than a generic prepaid line. Neither airport source publishes reliable official opening hours for either counter, so don't assume 24/7 coverage from the counters' existence alone (see airport_sim_hours).
Airport counter hours ▾
Neither Ncell nor Nepal Telecom publishes fixed opening hours for their Tribhuvan International Airport counters, so this isn't confirmed as 24/7 the way Delhi's Airtel counter is. Recent traveller information suggests the counters are generally staffed around international arrivals, including some late-night flights — one traveller asking about a 10 PM arrival was told the counters would be open, though another response clarified they aren't 24/7 and generally stay open only until the last scheduled flight of the day arrives. Adding to the uncertainty, a firsthand report describes the Ncell counter being closed before 4 PM on at least one occasion, showing staffing can vary. The safer statement for a 1–3 AM arrival: don't rely on the physical SIM counter with the same confidence you'd have at Delhi's 24/7 Airtel operation — keep a backup data plan (an eSIM bought in advance) for that scenario.
