# Everest Base Camp Mobile Network Guide: SIMs, Coverage and Backup Communication

Mobile coverage changes by village, network, handset, power supply and weather. Set up a Nepal SIM or roaming plan before the trek, but keep maps, permits, insurance and emergency contacts offline because high-route connectivity can disappear.

## Treat coverage as a moving service

A signal at one village does not prove that the next stop has the same service. Network availability depends on the operator, local infrastructure, handset, weather, power and the position of the trail. Nepal Telecom documentation describes GSM service in the Everest Base Camp and Gorak Shep area, but you should still plan for a missed call or an outage.

Local Planning Note · Amigo Treks Team
**Field advice**

Use connectivity to support the itinerary, not to decide whether a route or health situation is safe.

## Plan by route stage

Swipe to view table →

| Stage | Communication expectation | Preparation |
| --- | --- | --- |
| Kathmandu and Lukla | Best place to arrange SIM, roaming and downloads | Save the route, contacts, permits and insurance before walking |
| Namche and larger villages | More opportunities, but local outages and demand can affect access | Send essential updates and charge the phone early |
| Higher villages | Coverage can be intermittent or absent | Use offline maps, written contacts and agreed check-in times |
| Gorak Shep and Base Camp excursion | Treat calls and data as uncertain | Tell the guide where you are going and keep the phone protected from cold |

## SIM, roaming and phone setup

- Unlock the phone before travel and confirm whether your home provider supports Nepal roaming.

- Buy or register a local SIM through an authorised point when practical and keep the number with the operator.

- Save the guide, agency, insurer, emergency and accommodation contacts with country and local formats.

- Turn on battery-saving settings and download maps before the phone leaves strong coverage.

- Keep a written contact list because a dead phone and a missing signal create the same problem.

## Use the network for coordination

Agree the check-in rhythm with your guide or agency before the trek. Send family a realistic update window instead of promising daily contact. A missed message can reflect coverage, power, weather or a changed route. The guide's local communication plan remains more important than a traveller's personal data connection.

## Emergency communication limits

A phone cannot guarantee rescue. Emergency coordination procedures should identify who calls the insurer, evacuation operators, and medical support if a trekker falls ill. Never delay descent while searching for mobile signal.

## Offline communication checklist

- Download the full route map and mark the accommodation, health and turnaround points.

- Save permits, insurance, passport copies, emergency contacts and the written itinerary.

- Carry a power bank and keep the phone warm when batteries are exposed to cold.

- Agree a check-in time and a missed-contact escalation with family or the agency.

- Tell the guide before leaving the lodge for a side route, high viewpoint or Base Camp excursion.

Useful answers

## Frequently asked questions

Will my home SIM work on the Everest Base Camp trek?+
It depends on roaming, network coverage and handset settings. Confirm the provider's Nepal arrangement before departure and keep a local or operator-backed alternative.
Is mobile coverage available at Everest Base Camp?+
Coverage can be limited or variable. Nepal Telecom documentation describes GSM service in the Everest Base Camp and Gorak Shep area, but weather, power and local infrastructure can interrupt access.
Should I buy a Nepal SIM in Kathmandu?+
An unlocked phone and a local SIM can simplify calls, but use an authorised registration point and confirm the current process. Roaming may suit a short trip if it offers reliable support.
Maintain satellite messenger tracking and 24/7 Kathmandu operational desk standby.+
Agree the plan with the operator and guide before departure, including the local contact, insurer, check-in rhythm, missed-contact escalation and descent or evacuation process.
Do I need a satellite communicator?+
It can add a backup on a remote itinerary, but confirm whether the guide or agency already carries one, whether its use is lawful and who monitors messages. Never treat a device as a substitute for a conservative route plan.

## Sources & methodology

Changing prices, fees, aviation arrangements, local procedures, weather and lodge availability should be reconfirmed before travel. Altitudes, distances and walking times are approximate planning values.
