Buying a SIM Card or eSIM for Travel in Switzerland

As well as being a global financial capital and the home of fantastic chocolate and cheese, Switzerland is jaw-droppingly beautiful.

If you’re planning a visit, be aware that even a short train ride through the country will leave you with more photos of glistening lakes, rolling green hills, and snow-capped mountains than you know what to do with.

There’s plenty of free Wi-Fi in the cities and on public transport, but if you want to stay connected elsewhere, a local SIM is the way to go.

Like most other things in the country, they can be expensive. There is at least one option that’s surprisingly affordable, however, with great data speeds to go with it. Travel eSIMs, too, tend to be cheaper and more convenient than many local providers.

However you do it, here’s everything you need to know about staying connected in Switzerland. I’ve also included details on the odd roaming situation in Liechtenstein if your trip takes you there as well.

There are three cell service providers in Switzerland, plus various companies reselling service on each network. Swisscom and Sunrise have the largest networks, while Salt’s coverage is slightly lower but still covers 90%+ of the population.

Switzerland isn’t a cheap country to visit, and that’s equally true for cell service as anything else when buying from the main providers.

As it often does elsewhere in the world, however, Lyca Mobile offers lower costs as long as you’re happy to buy from convenience stores and other small retailers, and don’t expect too much in the way of support when getting set up.

Since it had the cheapest prices and uses the excellent Swisscom network, that’s the company I went with.

Depending on how much data you need and how long you’re in the country for, it may well be cheaper to just not bother buying a local SIM card and use a travel eSIM instead.

For longer stays and large data needs, it’s a different story, but even then, you’re not paying much to stay connected compared to how expensive everything else is in Switzerland!

I’ve generally found Instabridge to have the cheapest prices for Switzerland, as long as your requirements fit within one of their small number of package choices.

If you’re heading to Liechtenstein (or indeed, almost anywhere else in Europe) as well, though, go for this regional option from easySim instead: it’s only slightly more than the single-country version and means you’re covered in both countries.

Prices for those two companies, as well as the others that I regularly use around the world, are in the table below. I update the details every week, most recently on 1 Dec 2025.

Like most travel eSIMs, it’s data-only: you don’t get a local number. I use apps for everything from communication to transport these days, so the lack of a local number very rarely matters to me, but you might have different needs.

One of the good things about buying Lyca Mobile SIMs anywhere in the world is that there’s rarely a lack of places selling them.

That was as true in Zurich as anywhere else: a Thai restaurant near my accommodation had a sign in the window, as did a tiny convenience store a little further down the road.

The store owners were friendly and helpful, speaking good English. They also had brochures outlining the various options, which were in German but easily understandable. I chose the option that sounded best, and the owners took care of the rest.

They needed to take a copy of my passport, and then registered the SIM and generated forms to sign. The process took about ten minutes, including sending a code to buy the right data package.

I entered the following APN information from the brochure, rebooted my phone, and was up and running straight away.

Name: Lycamobile
APN: data.lycamobile.ch

I didn’t notice any Lyca Mobile signs at Zurich airport (although I wasn’t looking particularly hard), but other providers were available. You’ll definitely be able to get set up before leaving the arrivals hall if you want to, even if you have to pay more to do it.

Lyca Mobile SIMs are often available for free, as was the case at the shop I bought mine from. I bought a 10 CHF (~$12 USD) top-up, which was the smallest amount available at that particular store.

The prices for data, calling, and text bundles are, to be frank, all over the place. Depending on what specials are running and whether you’re buying online or in person, you can sometimes pay less for unlimited data than for 500MB of it!

At the time, I paid 9.90 CHF for 2GB of data. As I write this now, you can get unlimited data, domestic calls, and texts for 7.25 CHF ($9) when buying online, valid for a month. Expect things to have changed again by the time you’re reading this.

You can find the current offers on the Lyca Mobile site, or in the in-store brochures. Information on how to activate each package was also in the brochure.

Topping Up

Lyca Mobile

It’s possible to add extra credit to your Lyca Mobile SIM online, even with an international credit or debit card.

You can also drop into any store with a Lyca Mobile logo on display, tell them your phone number (you’ll get it in a text message after activation), and pay by cash/card there instead.

Instabridge

Topping up with Instabridge or easySIM is done by logging into the website or app and simply buying another package for Switzerland. There’s no need to install anything: it’ll just be available immediately.

Coverage was extremely good everywhere I went in Switzerland. That included major cities like Zurich and Lucerne, plus out in the countryside and on train journeys.

I had LTE service almost the entire time, and speeds were extremely quick, with downloads of 100Mbps+ not uncommon.

Switzerland is not part of the European Union or European Economic Area, so the free EU/EEA roaming regulations introduced in June 2017 don’t apply.

A few mobile companies in other EU countries do include free or discounted use in Switzerland even though they aren’t obliged to, but otherwise you’ll pay roaming charges when using SIM cards from outside the country.

In short, if you’re picking up a SIM elsewhere in Europe and plan to use it in Switzerland, carefully check the details first!

A Note on SIMs and eSIMs in Liechtenstein

The small principality of Liechtenstein sits between Switzerland and Austria. It uses the Swiss franc as its currency, but unlike Switzerland, is part of the European Economic Area (EEA).

As a result, EU/EEA mobile roaming regulations apply in this tiny area, but not its larger neighbor. This can lead to some confusing situations for international visitors.

Things are made particularly complicated by the fact that (a) some Swiss mobile operators also provide service in Liechtenstein, with the same or very similar network names, and (b) the principality is so small that you’re often in range of cell towers in both Switzerland and Liechtenstein at the same time.

If you buy a local SIM card in Switzerland and plan to use it in Liechtenstein, be sure to buy from Swisscomm, Salt, or one of their resellers like Lyca Mobile. You’ll get free roaming in Liechtenstein if you do. Sunrise, however, doesn’t offer this.

If you’re using a SIM card from elsewhere in the EA/EEU, you’ll get free roaming in Liechtenstein (within usual limits), but only if you’re connected to a cell tower inside the principality.

If you’re using a travel eSIM, you’ll need to either buy a regional Europe pack as above, or buy separate eSIMs for each country.

When using a Lyca Mobile SIM card, my phone took about half an hour to switch over to a local tower once I crossed over from Switzerland. Make sure yours has done the same if you’ve traveled through Switzerland and want to turn roaming on your EU/EEA SIM back on!
