Prepaid SIM cards & Wifi hotspots for Switzerland

Print this page

We had rented the Travelers Wifi based on this website and found it worked everywhere.

Must knows about Swiss SIM cards and alternatives

  • A prepaid SIM card for Switzerland requires your phone to be SIM-lock free.
  • Alternatively your can rent a Wifi hotspot for high speed internet wherever you go.
  • You'll also need a SIM card or mobile hotspot to use internet in the trains. There is no Wifi in most cases.
  • Switzerland is no EU member state, so don't assume low call and data rates even if you live in the EU. Double check with your provider.
  • Buying a Swiss SIM card or hotspot requires identification (passport or ID card).
TravelersWifi hotspot

The convenient TravelersWifi hotspot offers fast internet wherever you go.

Option 1: premium mobile Wifi hotspot (the best option)

A mobile Wifi hotspot for Switzerland, offered by Travelers Wifi: we tested this device and were impressed by the ease of use and speed. This hotspot was much faster than the Wifi in our hotel! We enjoyed having high speed internet available everywhere we went: in the trains, while hiking, and while relaxing out on the terrace.

  • It's fast. The hotspot uses the fast 4G network with speeds of up to 150 Mbps download and 50 Mbps upload, depending on the location. When we tested it, we measured a 25-40 Mbps download speed and 17 Mbps upload speed. That's really fast: it's enough for streaming video, Skyping, uploading your photos to the cloud, and anything else you need to do online.
  • No data limit! There is absolutely no data limit. You pay a fixed amount when you order the device, and you can be online all day long. Unlike many other providers offering unlimited data, there will not be a speed reduction after you've used a certain amount of data.
  • You only need one hotspot for the whole family. You can connect up to 10 devices like phones, tablets and laptops.
  • Easy charging. The hotspot continues to work when you connect it to the included charger at the end of the day. So you will keep your internet connection. Charging only takes an hour.
  • It's convenient. With your own hotspot, you do not need to replace the SIM card in your phone, so your phone number will continue to work and contacts stored on your SIM card will remain available. Also, this hotspot is an excellent solution for locked devices which cannot use any other SIM card. Even phones that don't work in Europe can get online as long as they can connect to a Wifi network. The hotspot is a lightweight small device that easily fits in any pocket. The dimensions are 11.2 x 7.6 x 1.6 cm.
  • Excellent coverage through the Swiss 4G Sunrise network.
  • No additional costs, all is paid in advance.
  • Knowledgeable helpdesk via phone and e-mail. We didn't need this, because it worked perfectly.


  • This is not the cheapest option. The price varies from CHF 3.60 to 21.95 per day (including shipping), depending on the rental duration. We think it's worth it as you will get very fast and unlimited connectivity, and you can connect multiple devices. This hotspot is affordable for demanding users, groups and families. Note that long-term rental (up to one year) is possible as well. Prices start at CHF 1.40 per day.
  • The hotspot only works in Switzerland and Liechtenstein. There is a slightly more expensive version that covers most countries world wide including Switzerland. This version also offers unlimited data, but there is a speed reduction to 3G if you use a lot of data (does not apply to Autria, Switzerland and Liechtenstein). 3G starts if you use more than 2 GB per day in the European Union or more than 500 Mb per day in other countries. The maximum speed will be available again the next day.
  • The battery doesn't last a full day but 10 hours at least. We recommend to turn it off if you don't need your devices to be connected while traveling. It's just one push on the button to turn it off or on. Connect it to the charger when you're in your accommodation. Make sure it's fully charged when you leave for your day trips. We experienced no issues following this procedure. If you expect to use it continuously and can't recharge daily, it's recommended to order along an extra battery.

How to use the Wifi hotspot

This is how it works:

  1. Order the Travelers Wifi device for the number of days you will be in Switzerland.

  2. Choose how to receive the device: delivery to your home address, a Swiss hotel, holiday home or any other address in Switzerland. Or reserve one to pick it up from the airport, several train stations, post offices or tourist offices.

  3. Once you have your device, open the package and press the button on the hotspot. It is already charged so you can use it immediately.

  4. The package also includes the hotspot password. Use it to securely connect all your devices (phone, tablet, etc.) to the Wifi network of the hotspot. You're online now! The SIM card in your phone can stay in place and will work as normal.

  5. Use it wherever you go, and connect it to the included charger when you're back at your accommodation.

  6. On the last day of your stay, you can put the device in the return envelope and return it where you collected it, at a post office, or drop it in any of the Swiss Post mailboxes which can be found in any village. Instructions are in the package.

Option 2: budget prepaid SIM card for data/calls/text (recommended for regular usage)

We recommend the Europe & UK SIM card offered by SimCorner. It offers plenty of internet data, calls and text messages not only in Switzerland, but also the rest of Europe. It can be used for 30 days.

Where to buy

simcorner.com/europe-sim-card: more SIM cards for Europe (higher speed, suitable for tablets, etc.)
simcorner.com/price-beat-guarantee: best price guarantee


  • It's affordable: 12 Gb of data for € 25/$ 29. Even 1 Gb is plenty for the average holiday and regular usage, assuming you can access Wifi in your hotel or apartment. We've used less than 1 Gb in two weeks. 12 Gb is enough to share among multiple people, or to watch short videos.
  • Excellent coverage because it works with many network carriers, such as T-Mobile, AIS, Vodafone, Three, etc..
  • Good speed: 3G or 3.5G (HSPA+) in most countries, which isn't as fast as 4G, but very acceptable for normal usage. 4G is available in the UK, Sweden, Denmark, Austria and Ireland. During our test with this card, we measured a download speed between 2.2 and 11 Mbps and an upload speed between 1.4 and 5.6 Mbps.
  • You only need one SIM card for multiple devices: you can use your phone as a Wifi hotspot (test this before departure), so other devices of you or your family (tablet, laptop) can get online through your phone. Note that the speed may be reduced a bit if sharing the connection.
  • No additional costs, all is paid in advance.
  • Works in Austria, France, Germany, Italy, Liechtenstein, Switzerland and a lot of other countries.
  • Calls and text included: 3000 minutes (50 hours) of calls and 3000 SMS messages within and to all the mentioned countries. Exceptions: while in the UK, one can only call and send messages to UK phone numbers. While in Israel, only data will work. Calling and texting to other countries can be done through apps like WhatsApp and Skype.
  • Free incoming calls.
  • Always fits in your phone as it comes in standard, micro and nano format.
  • Affordable shipping: € 6.00-8.00 to most countries, €2.00 to the UK and free to Australia.


  • The SIM card can only be used in phones, not in other devices. Other devices can use the hotspot of your phone though.
  • Your phone needs to be SIM-lock free.
  • Your phone needs to work in Europe (quad-band and penta-band phones work in Europe and nearly everywhere else in the world).
  • You can't recharge the SIM card when the 30 days have expired or data is all used up. If you need more, you will need to buy another SIM card.

How to install the SimCorner SIM card

Please read the instructions. For your convenience we'll list the procedure below:

  1. Disable mobile data on your phone while traveling to Switzerland if you don't have a data plan from your home provider.

  2. Enable mobile data on your phone once you are in Europe. Turn off your phone, remove your SIM card, insert the SimCorner SIM card, and turn on your phone.

  3. Enable roaming data on your phone.

  4. You will now receive a text message letting you know that the configuration of your card has been started. The configuration normally takes a minute or two, but can take up to 30 minutes. Another messages will instruct you to turn your phone off and on to complete the setup.

  5. You should now be online. If you're connected to Wifi you can temporarily disable that to verify that you can still access the internet without Wifi.

  6. Your phone number is printed on the plastic card that contained the SIM card. Replace the first zero by "+44" as it's a UK number. This is the number people can call to reach your phone.

Option 3: search for alternatives

Do the above mentioned products not match your needs? Please find alternatives to explore here.

Wifi hotspots

Data SIM cards

Data and calls SIM cards

eSIM cards

eSIM cards are electronic SIM cards, so a physical card is no longer needed. This is supported by a limited number of phones.

Option 4: use your own SIM card

If you live in the EU, calls and internet usage on your cell phone cost the same whether you're in your own country or elsewhere in the EU. So you may not need to buy anything if rates, data speed and data amounts are just fine for your holidays as well. Do note that Switzerland is not a member state of the EU. Many providers do count Switzerland as a EU country. Some don't, so in that case you'll pay more.

Try to estimate how much you will call and how much data you will need during your stay. Check the rates of your provider for calls and data in Switzerland. It can still be cheaper to buy a SIM card or Wifi hotspot. For fast internet, and especially if you travel with multiple people, renting a mobile Swiss Wifi hotspot is an excellent option.

Must know: how to safely use free Wifi networks

You can use free Wifi hotspots, even if you don't have a SIM card or mobile Wifi hotspot. It's a good option if you don't use the internet often, or if your SIM card or hotspot as a data limit. Free Wifi hotspots are available at various places like hotels, stores and train stations. They can be accessed with a guest password or even without a password. The disadvantages of such hotspots are:

  • Availability is not guaranteed.
  • Speed is not guaranteed.
  • Safety and privacy are not guaranteed.

Regarding safety and privacy: there can be people snooping around on the same network that you are on. Even if you visit secured websites, they can see which websites you visit. If you visit unsecured websites (without https), they can see everything you do (including passwords and credit card numbers).

If you use a VPN (Virtual Private Network) to access the internet, you will always be on a secure encrypted connection. Free Wifi hotspots can then safely be used, and even unsecured websites are no longer a risk.

Using a VPN is easy: it is software that you need to install on your phone, tablet or laptop. You can turn it on when you need it, or automatically. There is very little to configure to make it work.

We use GooseVPN ourselves. We found it to be an affordable and very easy option. It can be installed on all of your devices for one price. There are no additional costs, no matter how much you use it. We opted for their lifetime deal, so we paid once and can use it on all our trips, forever.

Insider tips about mobile internet in Switzerland

  • Internet coverage is very good in 99% of Switzerland, but there may be no signal in some remote uninhabited areas.
  • In general, Wifi in hotels isn't bad at all, but we'd recommend not to rely on those networks alone if internet connectivity is important to you.
  • Shops at the airports of Geneva and Zurich sell SIM cards as well. However, buying a SIM card or hotspot online is much easier. You'll be able to use it immediately without loosing time, and you won't be depending on opening hours.
  • There are plenty of Swiss apps for public transport schedules, the weather and maps to make your stay more comfortable.
