About this eSIM

A Lucerne eSIM gets you connected across Switzerland the moment you touch down, no roaming fees and one-tap activation. Lucerne runs on quick 4G and 5G: expect a solid signal crossing the wooden Chapel Bridge, strolling the Old Town along the Reuss river, riding the cogwheel train up Mount Pilatus and taking the boat across Lake Lucerne. Coverage holds from the train station out to the lakeside villages and mountain lifts, so maps, timetables and rideshare apps all work from your very first minute.

In Lucerne the signal is most dependable around the old town, across the Chapel Bridge, and along the lakefront near the train station. It can weaken as you climb the surrounding peaks like Pilatus and Rigi, inside the mountain railways and cable cars. Activate your eSIM before you travel so you are online the moment you step off the train, and keep your home number on for calls. Sort your excursion tickets down by the water before the ascent thins your connection.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Good to know

Before you travel to Switzerland

Do I have to register a SIM here?

Switzerland requires registration for prepaid SIMs bought locally. A travel eSIM is not affected.

Local SIM-registration rules apply to buying a SIM in the country. A travel eSIM is a foreign profile roaming onto the local network, so you are not registering anything locally and there is no counter to queue at.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Lucerne?

Yes. Your Switzerland eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are Salt, Sunrise. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Lucerne?

Yes, where it has been deployed. 5G runs on Salt, Sunrise in Switzerland, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

How much data do I need for Lucerne?

These are Viasimo's sizing recommendations, not measurements of your trip. Maps, messaging and the occasional lookup run to roughly 1GB a week. Streaming, video calls or tethering a laptop push that to 3-5GB a week, and uploading photos and video moves past it faster still. The data calculator on this site works it out from how you actually use your phone. Sizing one tier up costs less than topping up part-way through a trip.

Is an eSIM cheaper than roaming in Lucerne?

Usually, though it depends on your own carrier. A roaming day-pass is charged for each day it is active whether you use the data or not, while a prepaid bundle is one up-front purchase for a fixed amount of data. The gap widens on longer trips. Check your carrier's published rate for Lucerne before you fly rather than taking our word for it.

How do I install my eSIM?

After checkout we email you a QR code. On your phone, open Settings, then Cellular or Mobile data, tap Add eSIM, and scan the code. Installation takes under a minute.

When does my Lucerne eSIM activate?

Your plan activates automatically when you arrive and connect to a local network, so your validity period only starts once you land.

Can I keep my regular number?

Yes. The eSIM is data-only and runs alongside your physical SIM, so you keep your home number for calls and texts while using Viasimo for data.

Can I top up or extend my plan?

Yes. You can buy more data or extend your plan at any time from your account before it expires.

Does it support hotspot and tethering?

Tethering is supported on most devices, so you can share your connection with a laptop or other devices.
