Mobile networks in Switzerland

Which networks your eSIM uses in Switzerland

Your eSIM connects to Swisscom, Sunrise and Salt, the three mobile networks in Switzerland. It joins the strongest partner network where you are, automatically. The eSIM cannot be locked to one carrier, so coverage shifts as you move between towns, valleys and mountain areas. No manual network selection is needed.

Switzerland has 129 mobile subscriptions per 100 people, so the networks are built for heavy everyday use. Your data plan is a data-only travel eSIM on a country plan. It has no local phone number. WhatsApp and app calls work over data, and your own SIM stays in the phone for calls and bank texts.

To get connected:

1. Buy the plan and receive the QR code by email, usually in minutes.
2. Install the eSIM on Wi-Fi before your flight.
3. Keep your own SIM in the phone for calls and bank texts.
4. Turn on the eSIM line when you land and let it join a partner network.
5. If data does not start, turn on data roaming for the eSIM line.

The APN is set automatically on most phones. You do not need to type network settings by hand.

Coverage and 5G in Switzerland

5G is the main generation on Swiss mobile networks, and coverage reaches most populated areas. 97 per cent of people in Switzerland use the internet, which reflects how far mobile and fixed networks reach. Expect data in cities, along main rail routes and in many resort towns, with weaker signal in deep valleys and high mountains.

Your eSIM uses the partner network with the strongest signal at your location. That automatic choice matters in a country with many valleys, because one carrier can be weak where another is strong. The phone moves between networks as you travel, without you changing any settings.

Indoor coverage varies by building, and remote hiking areas can have gaps. Download offline maps before long walks. Data use is the same as at home: maps, messaging and app calls all run over the mobile connection. Internet use is high across the country, so busy areas are well served.

Will your phone work in Switzerland

Your phone works in Switzerland if it supports eSIM and is carrier unlocked. Most recent iPhone, Samsung Galaxy and Google Pixel models meet both conditions. Check the eSIM setting in your phone menu and confirm the phone is not locked to your home operator before you buy a plan.

A carrier lock stops the phone from accepting another provider's eSIM. Most phones sold outright are unlocked, but phones bought on contract can be locked. Your home operator can confirm the status.

Swiss networks use standard mobile technology, so a recent unlocked phone with eSIM support has no compatibility problem. Keep your own SIM in the phone so calls and bank texts still arrive on your usual number while data runs on the eSIM.

Setting up before you fly

Install the eSIM on Wi-Fi before you fly and the days start when it first connects in Switzerland, not at purchase. The QR code arrives by email in minutes. Pay with Apple Pay, Google Pay or a card your bank confirms. Prices are in US dollars, shown before payment, with nothing added at checkout.

Plan sizes include 1, 2, 3, 5, 10, 20 and 50 GB, with lengths of 7, 15 and 30 days. Pick a size that matches your trip and add data to the same eSIM online later without a new QR code.

Before departure, install the eSIM, label it clearly and leave it switched off. On arrival, switch it on and enable data roaming for that line if data does not start. Your own SIM stays active for calls and bank texts. Network details were checked on 2026-10-31, with subscription and internet figures from ITU via the World Bank.
