Switzerland eSIM

Switzerland's networks reach almost everyone with 4G or 5G, from the Zurich trams to the Zermatt valley. What catches visitors out is that Switzerland isn't in the EU, so many European SIMs don't roam here like at home, and Basel's airport is actually in France.

What a week of data costs in Switzerland

Prices for 7 days of data, checked on 2 November 2026. The EU's roam-like-at-home rules don't cover Switzerland; operators choose whether to include it. Daily passes charge for each day you use the phone abroad, per phone.

For a family of four on Verizon, that's $336 for one week. If you're on O2, Three or a current Telekom plan, you may need nothing extra; on an older or cheaper plan, check before you board.

Landing at Zurich (ZRH), Geneva (GVA) or Basel (BSL)

Switch the kimsim line on as the plane taxis to the gate, and turn on Data Roaming for that line only.

Entry first. British visitors can stay up to 90 days in any 180 without a visa, counted across the whole Schengen area, which includes Switzerland. Your passport must be less than 10 years old on arrival and valid for 3 months after you leave. The EU's Entry/Exit System may take your fingerprints and photo at the border, so expect queues. Other nationalities should check before booking.

Zurich: the railway station is under the Airport Centre, and about 13 trains an hour reach Zürich HB in 9 to 13 minutes. Direct trains also run to Lausanne, Basel and St. Gallen, so buy your ticket in SBB Mobile on the way to the platform. The airport gives you eight hours of free Wi-Fi, which helps if you still need to install. Swisscom staff are at the airport if you want a local SIM; with your eSIM working, walk on.

Geneva: the station is directly beneath the terminal, with up to seven trains an hour and 7 minutes to the city centre. If you're staying in a Geneva hotel, hostel or campsite, ask for the Geneva Transport Card, which covers that ride. The airport also has a France Sector for flights to and from France and for French-side car hire. Head out that way to Chamonix or Annecy and your Switzerland plan stops working.

Basel EuroAirport: the airport is entirely on French soil, with a Swiss sector inside. Your phone may join a French network in the terminal, where a Switzerland plan has no data. Bus 50 leaves from the Swiss sector arrivals area every 7 to 10 minutes and reaches Basel SBB station in about 20 minutes. Your eSIM picks up a Swiss network once the bus crosses the border. Download your hotel details before you land.

Networks and coverage

Switzerland has three networks: Swisscom, Sunrise and Salt. This plan uses Sunrise and Salt, and your phone shows their names, not kimsim. The networks your plan uses are listed above.

The federal regulator, ComCom, says almost 100% of the population had 4G by the end of 2025. Sunrise covered more than 99% with 5G, and Salt reports 99.9% across all its network generations. Sunrise switched 3G off in mid-2025, so an old 3G-only phone won't work on it.

That's population, not land. Expect gaps in deep side valleys, on high hiking trails and in long tunnels. The Gotthard Base Tunnel alone runs 57 km under the Alps.

Borders. Switzerland touches France, Germany, Austria, Liechtenstein and Italy, and many towns sit right on the line. Around Geneva, Basel, Lake Constance and Lake Lugano, your phone can latch onto a foreign network, where this plan has no data. If that happens, choose Sunrise or Salt by hand.

Region by region

• Zurich: dense and well covered. Old town cellars and basement bars can be weak indoors.
• Geneva and Lake Geneva: good in Geneva, Lausanne and Montreux. Along the south shore, France is across the water, so watch which network your phone picks.
• Bern, Interlaken and the Jungfrau: fine in Bern and Interlaken. Up the valleys to Grindelwald, Lauterbrunnen and Wengen, expect weaker spots. The Jungfraujoch station sits at 3,454 metres; save your tickets before you go up.
• Zermatt and the Matterhorn: fine in the village. Download maps and trail routes before any high walk or glacier trip.
• Lucerne: good in town and on the lake boats. Summit trips such as Pilatus and Rigi go through cable cars and cogwheel lines, where signal can come and go.
• Ticino: Lugano and Locarno are Italian-speaking and close to Italy. The Italian border is close on lake trips, so check your network.
• St. Moritz and the Engadin: high, remote valleys. Towns are fine, but passes and ski runs can be patchy.

This is general guidance, not a coverage map. Liechtenstein is a separate country; see the Liechtenstein eSIM if you're staying there.

Trains, boats and mountain railways

Most visitors get around Switzerland by train, bus and lake boat. SBB Mobile shows the timetable and sells tickets, and with EasyRide you swipe to start a journey and the app works out the fare. If you bought a Swiss Travel Pass, save it in your phone's wallet or as a PDF, so it opens without signal.

Mountain railways and cable cars climb through tunnels and steep rock, and signal can drop for a few minutes. Load tickets and the day's weather before you board, not on the platform at the top.

Apps worth having

• SBB Mobile for trains, buses, trams and boats, including tickets for trips abroad.
• Uber works in Zurich and Geneva, and books local taxis there too. Set it up at home, because sign-up can send a code by text to your usual number.
• MeteoSwiss, the federal weather office's app, gives local and mountain forecasts and pushes severe weather warnings. Check it before any cable car.
• swisstopo carries the official national maps, and you can download them for areas with no reception.
• WhatsApp is how many hotels and guides message you. Keep your WhatsApp number working abroad.
• Rega, the air rescue service, answers on 1414 in Switzerland.

SIM and phone rules

Every Swiss SIM needs an ID check. Under the federal surveillance ordinance, the seller must check your passport, ID card or foreign national identity card when they hand over or first switch on a mobile line, and keep a copy. Sunrise does this online: you upload your ID and record a short video selfie. A Swiss tourist SIM also gives you a new Swiss number, and logging in to activate a Swisscom eSIM can need a code sent to a Swiss number.

A travel eSIM installed at home skips the ID upload and the shop. It's data only, so your home number stays in the phone for calls and texts.

Common mistakes

• Assuming your EU plan covers Switzerland. It's up to your operator, not EU law, and older plans can charge per 50 KB. Keep roaming off on your home line. Why roaming goes on for the kimsim line only
• Expecting data at Basel airport. The terminal is in France. Wait until the bus has crossed into Switzerland, or install on Wi-Fi before you fly.
• Day trips over the border. Chamonix, Lake Como and Konstanz are a train ride away but outside a Switzerland plan. The Europe plan covers both sides. How regional plans work
• Starting the plan on a stop-over. If you change planes in Frankfurt or Paris, keep the kimsim line off until you land in Switzerland. If your plan started early
• No way to call for help. 112 works in Switzerland, alongside 117 for police and 144 for an ambulance. A data-only eSIM can't dial them, so use your home line or any local phone.

How we put this page together

We checked operators' own pages, Swiss federal law and the regulator's coverage report, carriers' roaming price pages, airport and transport operators' sites and the other sources noted above on 1–3 November 2026, and we'll keep them up to date. Vodafone UK's and EE's pages didn't show their Switzerland rates when we checked, so they aren't in the table. We haven't measured speeds or coverage in Switzerland ourselves, so coverage notes are general guidance, not a map. kimsim sells the eSIMs on this page.
