Find out where to buy a SIM card, a comparison of the mobile internet providers, the best 4G/5G network in Switzerland, up to date prices, my recommendation, restrictions on EU data roaming and more about eSIMs for Switzerland.

Since I have family living in Basel I visit Switzerland a couple times per year. Every time I pop into stores of Salt, Swisscom and Sunrise to get the latest prepaid SIM card info for you.

Be aware that phone stores in Switzerland only sell physical prepaid SIM cards. That means if your phone is not fitted with a SIM card slot (newer iPhones), you will have to order an eSIM on the internet and they can not help you in Salt, Sunrise and Swisscom stores.

My recommendation

Traveltomtom recommends a Swisscom prepaid sim card for a trip to Switzerland. They have the best 4G/5G network in Switzerland and have a prepaid sim card for approximately $20 USD that gives you unlimited high speed data for 10 days.

Prepaid SIM cards you buy in Switzerland do not include EU data roaming, that means they are only valid in Switzerland.

If you are traveling onwards in Europe then I recommend buying a SIM card for Europe that also works in Switzerland or one of the international travel SIM cards with data.

The easiest way to stay connected when traveling to Switzerland is actually an eSIM and they already start from just $1 USD. Traveltomtom recommends a Jetpac eSIM for Switzerland with 10 GB for just $11 USD.

For a detailed guide check out my comparison of the best eSIMs for Switzerland in 2026.

Make sure your phone is unlocked before buying a prepaid SIM card in Switzerland otherwise it won't work. If you are unsure about this then contact your mobile internet provider in your home country before your trip.

Best prepaid SIM card for Switzerland in 2026

Switzerland is one of the most expensive countries in the world. However, prepaid SIM card plans for tourists are not too bad and for 20 CHF ($25 USD) you basically get 10 days unlimited high speed data in Switzerland.

Swisscom has excellent 4G/5G coverage even in the mountain areas and off the beaten path and is therefore rated as the best prepaid SIM card in Switzerland in 2026.

Reminder that a Jetpac eSIM for Switzerland with 10 GB is only about $11 USD. So if your phone is eSIM compatible I would consider the convenience of an eSIM when traveling to Switzerland. For more info check out my comparison of the best eSIMs for traveling to Switzerland in 2026.

The main issue with Switzerland prepaid SIM cards is that they are only valid in Switzerland and NOT in the rest of Europe. If you only visit Switzerland on your trip to Europe then perfect. Otherwise it is worth checking the my comparison of the best Europe travel SIM cards in 2026.

After comparing Swisscom to Salt and Sunrise I came to the following conclusions:

• Swisscom has the best 4G/5G network in Switzerland in 2026
• most tourist destinations in Switzerland are covered with a good 4G/5G signal by all mobile internet providers
• Salt and Swisscom offer unlimited high speed data per day
• All data is ONLY valid in Switzerland, EU data roaming with Swiss prepaid sim cards is at extra costs

Swisscom offers unlimited data for 2 CHF per day at the fastest and most extensive mobile network in Switzerland and is therefore the best prepaid SIM card in Switzerland in 2026.

Why buying a sim card for Switzerland

Most hotels, bars and restaurants have free WiFi, yet Traveltomtom still recommends to get a sim card for Switzerland to stay connected and have a working data connection on your phone. Life is simply so much easier these days when you have internet on your phone. Think about ordering an Uber, get directions on Google Maps, finding a hotel, supermarket, restaurant and so on. Many reasons for you to get a sim card for Switzerland. And what about emergency situations or checking your banking apps?

Buying a local prepaid sim card on arrival in Switzerland is easy or simply order an eSIM for Switzerland on the internet, even easier. It will make your trip to Switzerland much more fun.

Also simply don't rely on WiFi, some hotel WiFi's are slow, have little reach in your room and above all public WiFi is an UNSECURED network. Your data is not protected. The use of a VPN is recommended.

Being a full time nomadic travel blogger since 2012 I have been looking for the best ways to get connected in more than 170 countries around the world.

Swiss prepaid sim cards and EU data roaming

HEADS UP! Switzerland is a European country however, it is NOT PART OF THE EU!

That means that prepaid sim cards that you buy in Switzerland do NOT include free EU data roaming. Meaning if you buy a sim card in Switzerland, your data allowance is only valid in Switzerland and when you cross the border into Austria, Germany, France or Italy your sim card stops working!

Basically if you want to use your Swiss sim card for traveling in Europe you have to pay an extra daily fee. Totally NOT recommended!

For more info on EU data roaming check out my guide with tips and tricks for buying a local prepaid sim card on arrival in Europe.

Prepaid sim cards from Switzerland are the worst for traveling in Europe, but good news is that you can easily buy prepaid as well as eSIMs for Europe online and they are even much cheaper than prepaid Switzerland sim cards.

Check out Traveltomtom's comparison of the best (e)-sim cards for traveling in Europe in 2026. Order online and arrive prepared for your trip to Europe.

Where to buy a sim card for Switzerland

International Airport on arrival

The most convenient place to buy a prepaid sim card on arrival in Switzerland is at the international airport. There are 3 main international airports in Switzerland: Basel, Geneva and Zurich.

At Geneva Airport there is a SIM card store and you can also buy a tourist SIM card at the currency exchange. You find prepaid SIM cards from Lycamobile, Lebara and Yallo.

Check out my guide for buying a SIM card at Geneva Airport in 2026 for more info.

Are you arriving at Zurich Airport then there is a small SIM card shop in the duty free area opposite the luggage belts, but it has very limited opening hours.

The Zurich Airport is connected to a shopping mall where you can find a Swisscom and a Salt store that sells prepaid sim cards for tourists. For more info check out my guide for buying a SIM card at Zurich Airport in 2026.

Phone store in the city center

If you missed the chance to buy a Switzerland prepaid sim card at the airport your best bid is to go to any of the official retail stores in the city center. They are in every big city or shopping mall. Just go to Google Maps and type in the by you preferred store and locate the nearest one to your hotel.

Convenience stores and gas stations

They also sell Swiss sim cards at gas stations and convenience stores, but you will have to do the activation and registration process all by yourself and there is of course no service or help from the staff. Therefore Traveltomtom does not recommend this in general for tourists.

Online

There are multiple options of ordering a sim card for Switzerland online.

If your phone is eSIM compatible then the easiest way is ordering a Switzerland eSIM on the internet. Airalo, SimOptions and Jetpac are some of Traveltomtom's most recommended eSIM providers.

Traveltomtom also wrote the ultimate guide for buying an eSIM for Switzerland in 2026 with much more details and an answer to all FAQ about using eSIMs.

If your phone is not eSIM compatible you can order a physical prepaid sim card for Switzerland via SimOptions.

Registration process prepaid sim card in Switzerland

When buying a prepaid sim card in Switzerland you will need to bring your passport. A copy of your passport will be taken in the store and your new Switzerland sim card will be registered on your name and passport number. You receive a physical prepaid sim card that comes with a phone number that starts with +41.

If you want to avoid this registration process for some reason then you can order an international prepaid sim card for Switzerland or get yourself an eSIM for Switzerland. If you order a sim card for Switzerland on the internet you only need your email address, there is not ID-verification required.

Best 4G/5G mobile network in Switzerland in 2026

Like most things in Switzerland the mobile data network is also very well organized. Basically everywhere in the country apart from very remote places in the mountains are covered with a 4G/LTE or 5G signal.

Switzerland has a very good 5G network as of 2026. Below we compare the Switzerland network coverage maps of Sunrise, Swisscom and Salt to find the best 4G/5G network in Switzerland in 2026.

Sunrise Switzerland 4G/5G network coverage

Salt Switzerland 4G/5G network coverage

Swisscom 4G/5G network coverage

Although the above mobile data network coverage maps are updated for 2026 they are not 100% accurate. However, they are a great reference to compare the 4G/5G networks of the mobile internet providers in Switzerland in 2026.

What we can see from the above 4G/5G network coverage maps from the Swiss mobile internet operators is that every tourist destination in Switzerland is covered with an excellent 4G/LTE and even a 5G signal.

Traveltomtom comes to the conclusion that Swisscom has the best 4G/5G network in Switzerland in 2026 with Sunrise being a good runner up and Salt has the smallest 4G/5G network in Switzerland.

Prepaid SIM card prices in Switzerland in 2026

Below you will find the latest prices for prepaid SIM cards if a tourist would walk into any Sunrise, Swisscom or Salt phone store anywhere in Switzerland.

Final thoughts on buying a prepaid SIM card in Switzerland

Personally I nowadays always use an eSIM for Switzerland, simply because it is so convenient. But also because eSIMs for Switzerland include EU data roaming and prepaid SIM cards you buy in Switzerland are only valid in Switzerland.

I like the convenience being connected when the plane lands and not having to go to a SIM card shop. However, if you are visiting Switzerland for a longer period of time and you use a lot of data it is worth it to hop into a Swisscom phone store and get a local prepaid SIM card.
