From the lakes of Lucerne and Geneva to the peaks of Zermatt, Interlaken and the Jungfrau region, Switzerland is a dream to explore by train, cable car and on foot. You will use your phone for SBB train tickets and connections, mountain weather, hiking maps and booking your next stop.
Roaming in Switzerland is expensive for almost everyone, including EU residents, because Switzerland is not covered by EU roaming rules. A travel eSIM avoids that. Install it before you go and connect as soon as you land in Zurich or Geneva. Simhop compares current Switzerland eSIM plans below.
Mobile networks and coverage in Switzerland
Switzerland has three mobile operators: Swisscom, Sunrise and Salt. Swisscom is known for the best coverage, including in mountain areas and tunnels. Sunrise and Salt are also strong in cities and along major transport routes.
Coverage is excellent in cities, on trains and at most mountain resorts, and 5G is widely available. Even many high-altitude areas such as Jungfraujoch and Gornergrat have signal. Remote hiking trails and deep valleys can still have gaps.
How much data do you need for Switzerland?
For a one-week city and lake trip, 3 to 5 GB is usually enough. Hiking and train trips with constant connection checks, weather updates and photo uploads are more comfortable with 5 to 10 GB. Our guide How much data do I need? helps you plan.
Combining Switzerland with Italy, France, Austria or Germany? Many Europe eSIMs include Switzerland, but not all, so check the coverage list before you buy.

FAQ: eSIM for Switzerland
Does EU roaming work in Switzerland?
No. Switzerland is not in the EU, so EU roaming rules do not apply. Many carriers charge high rates, which is why a travel eSIM is often the cheaper choice.
Is Switzerland included in Europe eSIMs?
Often, but not always. Some Europe plans exclude Switzerland, so check the coverage list carefully before you buy.
Which network is best in Switzerland?
Swisscom generally has the best coverage, especially in the mountains. Sunrise and Salt also work well in cities and along main routes.
Is a Swiss prepaid SIM better than an eSIM?
A local prepaid SIM requires ID registration and a shop visit. A travel eSIM is usually more convenient for short trips, while a local SIM can be worthwhile for longer stays.
Do I need an eSIM for driving through the Gotthard Tunnel?
Not specifically, but traveling through Switzerland on the way to Italy can trigger expensive roaming on your home SIM. A plan that covers Switzerland avoids this.
