Nepal eSIM Guide 2026: Kathmandu, Pokhara and Trekking Connectivity
Everest Base Camp, Annapurna and Kathmandu chaos — how much data you need in Nepal and exactly where mobile coverage stops on the trails.
Nepal is two very different connectivity stories: cities and lowlands are well covered, and the high trails are a lottery. A travel eSIM handles the first part properly and lets you plan sensibly for the second.
Short answer: 5 GB covers a week in Nepal. Kathmandu and Pokhara have good 4G; on Everest Base Camp and Annapurna routes coverage exists in some villages and vanishes between them. Download offline maps and expect to be offline for stretches.
Why an eSIM in Nepal
Local SIMs require passport photos and registration at a shop — a chore on arrival in Kathmandu. A travel eSIM works the moment you land, so you can find your hotel pickup and confirm your trek permits without hunting for a counter.
Coverage in Nepal
A travel eSIM rides Ncell or Nepal Telecom. Realistically:
- Good: Kathmandu, Pokhara, Chitwan, Bhaktapur, main highways.
- Intermittent: lower Annapurna and Everest trail villages (Namche has service; the passes do not).
- None: high passes, glacier sections, most of the upper Khumbu.
Teahouses increasingly sell Wi-Fi vouchers — slow but usable for a check-in message.
How much data do you need?
- City + short trek: ~5 GB.
- Longer trip with photo uploads: 8–10 GB.
- Hotspot / remote work from Pokhara: 15 GB+.
Set up before you fly
- Buy a Nepal eSIM sized to your trip.
- Install it at home — see the install guide.
- Land, enable the eSIM and turn on Data Roaming for that line.
Trekking tips
- Download offline trail maps (Maps.me or Gaia) before leaving Kathmandu.
- Tell family your offline windows so silence is expected, not alarming.
- Carry a power bank and solar option — teahouse charging costs money and time.
- Altitude drains batteries as much as it drains you.
The bottom line
Nepal is best approached with good data in the cities and honest expectations on the trail. Install a Nepal eSIM before you fly, cache your maps in Kathmandu, and enjoy the disconnection up high.
Trek rule: assume no signal above the last big village. Anything you get is a bonus.
