How does Simbye eSIM work for Switzerland?
Get connected in under 2 minutes
Buy it and set it up at home
The email with the setup link and QR code arrives right after payment. Tapping the link installs the eSIM, or you scan the QR code with your camera. Do this on Wi-Fi at home, not at the gate – you need internet once to install it.
Switch it on in Switzerland
After landing at Zurich (ZRH), Geneva (GVA), Bern-Belp or Lugano, turn on mobile data and data roaming for the Simbye line and your phone does the rest. One special case is EuroAirport Basel-Mulhouse: it sits entirely on French soil and the Swiss networks there were switched off in 2016. Your Swiss eSIM only kicks in once you are in Basel.
Travel, and top up if you need to
The plan only starts counting with your first connection to a Swiss network, not at purchase. Hotspot for a laptop or tablet is allowed. When the data runs out you simply top up the same eSIM – nothing to reinstall, nothing to rescan.

Make sure your device supports eSIM before purchasing
Which networks will you be on in Switzerland?
The eSIM connects to the Swiss networks of Swisscom, Sunrise and Salt on its own – nothing to set up, no APN to type in.
Average measured mobile internet performance, nPerf barometer (measured 01.01.2025 – 31.12.2025). What you actually get depends on where you are, the time of day and your phone.
In Switzerland this eSIM runs on the country's three networks: Swisscom, Sunrise and Salt. As soon as you switch on data roaming for the Simbye line, your phone picks whichever network has the better signal and hands over on its own – there is nothing for you to set up. Close to the border it can latch onto the network next door instead: the German one in Basel, the French one in Geneva, the Italian one in Chiasso, and the same happens in Kreuzlingen across from Konstanz. Then nothing loads even though the bars look full. The fix takes half a minute: toggle airplane mode, or turn off automatic network selection in your settings and pick a Swiss network by hand.
Sunrise reaches around 99.8 percent of the population and says it runs the country's largest 5G network across more than 700 municipalities, Salt is at roughly 99 percent, and Swisscom's build-out extends far into the mountain valleys. In Zurich, Geneva, Basel, Bern, Lausanne, Lucerne, Winterthur, St. Gallen and Lugano you will simply notice fast internet, and the same goes for the valley towns of the holiday regions: Interlaken, Grindelwald, Lauterbrunnen, Zermatt, Davos, St. Moritz, Montreux, Locarno. But population coverage is not land coverage, and a large part of Switzerland is rock. Salt's own coverage map still shows white spots in Uri, Valais, Graubünden, Ticino and the St. Gallen highlands. On hiking trails above the villages, on mountain passes and in tunnels the connection can drop – so download your map and route down in the valley before you head up.
eSIM or a local SIM card in Switzerland?
| Compared | Simbye eSIM | Local SIM card |
|---|---|---|
| ID and registration | No registration, no passport at a counter | Swiss law requires an identity check for every SIM, you have to show a passport or ID |
| When it works | Set up at home, online the moment you land in Zurich or Geneva | Only after arrival: find a shop, opening hours, queue, activation |
| Where you get it | By email, minutes after purchase | Operator store, kiosk or airport counter in Zurich and Geneva |
| Network | Swisscom, Sunrise and Salt, your phone takes the strongest | Only the one network of the shop you bought the card from |
| Data and duration | Prepaid, 1 to 50 GB or unlimited, 7 to 180 days | Fixed local bundles, changing means buying another card |
| Your own number | Stays active, WhatsApp and SMS codes still reach you | If your phone has only one SIM slot, your number stays in the hotel room |
| Swiss phone number | No, data only, no calls and no SMS over the network | Yes, Swiss number included, but with mandatory registration |
| Topping up | In the app or via the link, the same eSIM stays installed | Top up in a shop, at a machine or online with a Swiss payment method |
Roaming, a local SIM or an eSIM – what actually matters in Switzerland
How expensive mobile internet gets in Switzerland is decided by your plan at home, and the rules vary widely: some tariffs bill Switzerland per megabyte, others file it under a separate country group, others include it. That is the trap – most people only notice on the bill after the trip.
What runs up the bill is rarely streaming, it is the small stuff: navigation in the car, the timetable at the station, the forecast before a hike, photos into the family chat. There are other reasons to want a separate data line here as well. Anyone travelling from far away rarely had cheap roaming in the first place. A second line keeps the work phone from costing anything on holiday. And some allowances are simply gone after five days.
The local card has a hurdle of its own: Swiss law requires an identity check for every SIM sold in the country, so you stand in a shop with your passport. To be fair: check your own plan first. If Switzerland is explicitly listed with your data allowance, you may not need anything at all for a weekend. If it is missing, or you only find it in the fine print under a different country group, a fixed amount of data paid for in advance is the calmer option.
Coverage of the Switzerland eSIM: where you have signal and where you don't
Switzerland has three mobile networks and this eSIM uses Swisscom, Sunrise and Salt. Sunrise reaches around 99.8 percent of the population and says it operates the country's largest 5G network across more than 700 municipalities, Salt sits at roughly 99 percent, and Swisscom extends far into the mountain valleys. In everyday terms: everything runs smoothly in Zurich, Geneva, Basel, Bern, Lausanne, Winterthur, Lucerne, St. Gallen and Lugano, and equally so in the valley towns of the holiday regions – Interlaken, Grindelwald, Lauterbrunnen, Zermatt, Saas-Fee, Davos, St. Moritz, Arosa, Montreux, Locarno.
Population coverage is not the same as land coverage, though, and much of Switzerland is rock with nobody living on it. Salt's coverage map still shows white spots in the cantons of Uri, Valais, Graubünden, Ticino and St. Gallen; Sunrise and Swisscom are denser there, but not seamless either. In practice: down in the valley yes, up on the ridge maybe not. If you are heading out on trails, over passes or through mountain tunnels, download your map, route and timetable beforehand instead of counting on a signal.
A second point concerns the borders. Basel, Geneva, Chiasso and Kreuzlingen sit right against Germany, France or Italy, and phones there happily latch onto the foreign network next door – then nothing loads even though the bars look full. Briefly turning off automatic network selection and picking Swisscom, Sunrise or Salt by hand fixes it in under a minute.
Every SIM card sold in Switzerland needs an ID check
This is what surprises most travellers: Swiss law requires an identity check for every SIM card sold in the country. For a local prepaid card you stand in a shop with your passport or ID, during opening hours, and fill in a form. This eSIM arrives by email, with no counter, no registration and no contract – you set it up at home and land with a line that already works.
The second point is a matter of honesty: this is a data-only plan. There is no Swiss phone number, you cannot make calls over this line and you cannot receive SMS over the network. Your own number stays active alongside it – WhatsApp, calls over the internet and SMS codes to your home number all keep working.
