Nepal’s international dialling code is +977. NTB notes that mobile coverage is not available in some rural Himalayan locations. Make a plan that does not depend on being connected throughout a journey.
- Ask a mobile provider about current registration requirements, coverage for your destination and the full cost of the plan you are considering.
- Save accommodation details, transport confirmations, essential contacts and document copies in a form you can open without mobile data.
- Charge your phone and power bank before departure. Protect them from water and keep a suitable charging cable accessible.
- Agree on a check-in plan with someone you trust, including what they should do if you miss a check-in.
- Test any offline resources before leaving connectivity. A bookmark alone does not prove that a map or article has been downloaded.
TrailNepal’s current test build does not provide offline map downloads, GPS recording or emergency messaging.
