Nepal IMEI Registration and Phone Signal for Trekkers

Nepal's telecoms regulator, the Nepal Telecommunications Authority (NTA), runs a Mobile Device Management System (MDMS) that checks every phone's IMEI on local networks. Tourists using a Nepali SIM are generally allowed about 15 days before a foreign phone must be registered online, while a travel eSIM or UK roaming avoids the local SIM process for most treks.

Last checked: 15 October 2026. NTA has not published one clear English rule for visitors, and enforcement has been patchy. Check the NTA MDMS portal, the NTA website and GOV.UK Nepal travel advice before you travel.

Nepal MDMS rules: the short answer

• What MDMS does: it lets NTA track and block phones by IMEI, to stop smuggled and stolen handsets.
• Tourists on a Nepali SIM: the most widely reported rule is that you can use a foreign phone for 15 days, then it must be registered on the MDMS portal.
• Registering: online, free, with your passport, visa and entry details. Registration is reported to last until your visa expires.
• Roaming and travel eSIMs: trekking guides report that short-stay visitors on roaming do not need to register. NTA has not confirmed this in a clear English notice.
• Enforcement: reports in 2026 say MDMS is still not fully automated, with some blocking done manually through the operators.

Who needs to register a phone in Nepal

MDMS applies to phones used on Nepali networks, Ncell and Nepal Telecom (NT Mobile). If you buy a tourist SIM at Kathmandu airport or in Thamel and put it in your UK phone, the network can see the phone's IMEI and check it against the MDMS list.

Reports from NTA officials and the Nepali press describe the visitor rule as:

• a phone can be used for about 15 days without registration;
• after that, the owner registers it on the MDMS portal, choosing the foreign applicant option;
• you upload a scan of your passport and visa or entry stamp, and give your home address and visa expiry date;
• the registration then stays valid until your visa expires.

Some reports say all foreign-bought phones must be registered within 15 days of entry, and one guide gives a 90-day grace period. Given that confusion, if you are trekking for longer than two weeks on a Nepali SIM, register as soon as you buy the SIM. It is free on the official portal.

Trekking and phone signal: Everest and Annapurna

Phone rules matter less on the trail than coverage does. Both Ncell and NT Mobile have 4G in the lower valleys, but signal fades as you climb. Based on recent trekker reports and Nepali telecoms coverage:

Ncell has previously announced plans for 4G near Everest Base Camp, but we have not seen confirmation that full coverage is live, and Ncell itself has said covering the whole route is not practical. Treat mobile data above 4,000 metres as a bonus, not something to rely on for safety. Carry a paper map, download offline maps, and agree check-in times with your trekking company.

Using a travel eSIM in Nepal

A travel eSIM connects to Nepali networks as a roaming connection. You install it at home, it switches on when you land at Tribhuvan International Airport, and you skip the SIM counter and the paperwork.

• Two networks on fixed-data plans. SimplySIM's fixed-data Nepal plans can use both Ncell and NT Mobile, which matters on the trail where one network may reach and the other may not. Our unlimited Nepal plans use Ncell only.
• Keep your UK number. Leave your UK SIM in place for bank texts and use the eSIM for data.
• No local number. The eSIM is data only. If your trekking agency needs to call you on a Nepali number, buy a local SIM too and register the phone if you stay over 15 days.

SimplySIM plans for Nepal

Prices were checked on 15 October 2026 and can change; the product page shows the current price.

For most treks, a 3GB or 5GB plan is enough: you will be offline for much of the day, and you can save data by downloading maps and music before you leave Kathmandu. See all options on our Nepal eSIM page.

If you also want a Nepali SIM

Some trekkers carry both: a travel eSIM for data from the moment they land, and a Nepali SIM for a local number that guides, drivers and lodges can call. If you do this, buy the SIM from an official Ncell or Nepal Telecom outlet in Kathmandu with your passport, and ask the staff whether your phone needs registering for the length of your stay. Your phone can hold both at once on most recent models, with the physical SIM slot used by either your UK SIM or the Nepali one.

Keep in mind that adding a Nepali SIM is what brings your phone into the MDMS rules. If your trek and travel days add up to more than 15 days, complete the registration on the MDMS portal in Kathmandu while you still have reliable internet, rather than trying to do it from a teahouse.

Saving battery and data on the trail

• Download offline maps for the whole route in Kathmandu.
• Turn off background app refresh and automatic photo backups until you are back on Wi-Fi.
• When there is no signal, switch to airplane mode. A phone searching for a network drains its battery fast, and cold makes it worse.
• Keep your phone and power bank inside your sleeping bag on cold nights.
• Teahouse charging and Wi-Fi usually cost extra at higher villages; carry small notes in rupees.

Checklist before you fly to Nepal

• Check your phone supports eSIM and is network unlocked on our device compatibility page.
• Install the eSIM at home and check the dual SIM settings so data uses the eSIM.
• Note your IMEI (*#06#) and keep a scan of your passport and visa on your phone.
• If you buy a Nepali SIM and stay more than 15 days, register on the official MDMS portal.
• Check that your travel insurance covers trekking at your planned altitude; GOV.UK has advice on this.

FAQs

Do tourists need to register their phone in Nepal?

Only if you use a Nepali SIM for more than about 15 days, according to most reports of NTA's rules. Registration is free on the MDMS portal. Short stays on roaming or a travel eSIM are generally reported as not needing registration.

Is there phone signal at Everest Base Camp?

Not reliably. Namche Bazaar usually has good 4G, but data becomes patchy above Dingboche and is often absent at Gorak Shep and Base Camp. Teahouse Wi-Fi fills some gaps for a fee.

Which network is better for trekking, Ncell or NT Mobile?

Trekkers often find Ncell good in the lower valleys and NT Mobile better at altitude. A plan that can use both gives you the best chance of a signal.

Can I use WhatsApp in Nepal?

Yes. WhatsApp messages and calls work normally on Nepali networks and on travel eSIMs, wherever there is enough signal.

Does the eSIM give me a Nepali phone number?

No. SimplySIM Nepal eSIMs are data only. Keep your UK SIM for calls and texts, or buy a local SIM if you need a Nepali number.
