A Switzerland eSIM from eSpeedz starts at $7.99 and gives you prepaid data on local Swiss networks, from Zurich and Geneva to mountain towns like Zermatt and Grindelwald. Install it from the QR code we email you, and it starts when your phone connects in Switzerland, so crossing the border doesn't trigger a roaming bill.
Switzerland isn't in the EU, and that matters for your phone. Here's how to stay connected on trains, lakes and mountain trails without the roaming shock.
Switzerland is where travelers most often get caught out by roaming. The EU's roam-like-at-home rules stop at the Swiss border, so a SIM or eSIM bought in France, Italy or Germany can start charging international rates the moment you arrive, and plenty of cheaper EU-only data plans leave Switzerland out altogether. From the US, your carrier's day pass bills you for each day you use it, which adds up on a ten-day loop through the Alps. A Swiss eSIM avoids both problems.
Trains are the backbone of most Swiss trips, and the SBB Mobile app is the one to install. It has live timetables for trains, buses, boats and cable cars, sells tickets, and shows platform changes. Its EasyRide feature lets you swipe to check in and out and then charges the best fare for the trip, but it needs mobile data and location access the whole time. Domestic trains don't offer free wifi to visitors: SBB's FreeSurf only works with a Swiss carrier's SIM, and free station wifi is limited to about 80 stations. The good news is that mobile coverage on Swiss rail is excellent, even deep inside Alpine tunnels like the Gotthard Base Tunnel.
Up in the mountains, coverage is impressively broad around resorts and lifts, but steep valleys and ridges can block signal on remote hikes. Before any big mountain day, install the Rega app, which can share your location with Swiss air rescue, and check MeteoSwiss for storm warnings, since afternoon weather in the Alps can turn quickly.

Plans connect to leading local 4G/5G networks in Switzerland. Popular stops for travelers:
Swiss apps are light on data; SBB says EasyRide uses about 1MB per hour while active. What uses data is photos and video of the scenery, maps on hikes, and video calls in the evening. A week of trains and day hikes fits comfortably in 5GB, or 10GB if you post a lot of video. For two weeks, or if you're uploading mountain footage every day, go for 20GB, and the 50GB plan is there for remote work. Every Switzerland plan runs 30 days.
June to September is hiking season, when high trails and mountain passes are open and lakes are warm enough for a swim. December to April is ski season in resorts like Zermatt, St. Moritz and the Jungfrau region. Late spring and autumn are quieter in the cities, though some mountain lifts close between seasons for maintenance, so check before you plan a summit day.
