Where does the Switzerland eSIM work?

The Switzerland eSIM provides data coverage across Switzerland (CH), including cities travellers visit such as Zurich, Lucerne and Interlaken. It is designed for use within Switzerland only.

When does the validity of the Switzerland eSIM start?

The validity of the Switzerland eSIM starts once the plan is activated, then counts down over the chosen period of 1, 7, 15, 30 or 180 days. You install the eSIM from the QR code before your trip and it begins its countdown when the plan activates.

How is the Switzerland eSIM delivered?

The Switzerland eSIM is delivered digitally by email as a QR code after your one-off, prepaid purchase. There is no physical SIM to collect or post; you scan the QR code to install it on your phone.

Can I still use my own phone number with the Switzerland eSIM?

Yes, your existing phone number stays active for calls and texts through your primary SIM while the Switzerland eSIM handles data. The eSIM adds a separate data line and does not change your current number.

What happens when my data runs out on the Switzerland eSIM?

When your data runs out on the Switzerland eSIM, you can buy another Switzerland eSIM plan to keep your data going. Plans are a prepaid, one-off purchase with no subscription, so you simply purchase again when needed.

Which phones are compatible with the Switzerland eSIM?

The Switzerland eSIM works on eSIM-compatible, unlocked phones. Check that your device supports eSIM and is carrier-unlocked before purchasing, as older or locked phones may not be able to install the eSIM.

Can I share the Switzerland eSIM connection by hotspot or tethering?

Whether hotspot or tethering is available depends on your device settings and the plan you choose for the Switzerland eSIM. The eSIM provides mobile data to your phone; a larger or unlimited data plan is better suited if you intend to share the connection.

What is the shortest and longest plan available for Switzerland?

The Switzerland eSIM offers validity periods of 1, 7, 15, 30 and 180 days, so the shortest plan lasts 1 day and the longest lasts 180 days. This makes it suitable for both a single-day visit and an extended stay of several months.

About this eSIM

Wedged between Lake Thun and Lake Brienz, Interlaken is your gateway to the Jungfrau region, and staying online makes the mountains easy. Your eSIM keeps you connected along the Höheweg promenade, up the cogwheel railways toward Grindelwald and Lauterbrunnen, and near the Harder Kulm funicular. Switzerland's networks are excellent, so expect strong 5G in town and reliable signal on the trains, with no roaming charges. Activate it on arrival and check SBB timetables or paragliding weather without a second thought.

In Interlaken the coverage is solid through the town centre, along the main street between the two lakes, and around the stations where most visitors pass through. It can drop as you head up into the mountains, through rail and cable-car tunnels, and out into the higher alpine valleys. Activate the eSIM before you arrive so it is ready when you step off the train, and keep your home number on for calls. Handy tip: download offline trail routes before heading up.

Pedro Castillo

I used Viasimo to travel home to California this year. The instructions were super easy to follow and I had no problems with the service for the whole 20 days that I used it. It was nice not to worry about

Magda Sutherland

Excellent service, and when I needed help the support team was right there. They answered within minutes and had me back online straight away, with no stress and no roaming surprises.

Rawiya Bikhazi

A complicated request was solved urgently within 24 hours of traveling. They are wonderful and I recommend it to everyone. Thank you Viasimo team!

Jonas K.

Landed in Tokyo, switched off flight mode and I was online before I reached passport control. No SIM-card queues, no surprise bill afterwards.

Viasimo is the easiest way to stay connected abroad: installed in minutes, working the moment you land, for a fraction of what roaming costs.
