Option 1: high-speed budget eSIM (recommended if your phone supports eSIM)
There are usually two of us traveling together, carrying two phones and two laptops. We need reliable high-speed internet all the time. We do not want data limits and we don’t want a separate SIM card for each device.
A mobile WiFi hotspot used to be the perfect solution for us. But eSIM plans have been getting better. I now install an eSIM on my phone, and configure my phone as a hotspot so that all devices can access the internet.
Do check if your phone supports eSIM. eSIMs are electronic, downloadable SIM cards. A physical SIM card is not needed. If your phone supports it, an eSIM is likely your best option for mobile internet in Switzerland, even if you don’t use as much data or only have one device.
The eSIM I use: the O2 Travel eSIM
Here’s why I recommend this eSIM to almost everyone:
- It’s only $24 for 30 days. Check the current price on www.esim.net/O2/Travel and apply voucher code MYSWISSALPS for a 5% discount.
- It includes 50 Gb of data, with no daily limits. I use about 0.5 Gb per day. If you would run out during your trip, you can easily buy another eSIM online.
- It allows your phone to be configured as a WiFi hotspot. So, you can share the data with multiple people and only need to buy one eSIM.
- It includes high-speed internet (up to 5G) and didn’t fail me a single time.
- It works in Switzerland but also in the rest of Europe. I used it in Germany as well.
- I rarely call during my trips but it also includes unlimited calls within the country you are in and 500 minutes of calls to other countries.
I compared a lot of eSIMs, and most cannot offer this. They are either much more expensive, don’t allow using the hotspot on your phone, don’t offer 5G, have daily limits, or a combination of issues.

Option 2: budget prepaid SIM card (recommended if you can’t use an eSIM)
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 in the rest of Europe. It can be used for 30 days.
Where to buy
- simcorner.com/europe-sim-card-12gb: details of the 12 Gb Europe & UK SIM card
- simcorner.com/europe-sim-cards: more SIM cards for Europe (higher speed, suitable for tablets, etc.)
- simcorner.com/price-guarantee: best price guarantee
Advantages
- It’s affordable: 12 Gb of data for $24. 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 (see simcorner.com/pages/about-us).
- Good speed: 3G or 3.5G (HSPA+) in most countries, 4G in some countries. 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 phones, laptops, and tablets of you or your family can get online through your phone. Note that the speed may be reduced a bit if you’re sharing the connection.
- No additional costs, all are paid in advance.
- Works in Austria, France, Germany, Italy, Liechtenstein, Switzerland, and a lot of other countries.
- Unlimited calls and text to standard Europe and UK landlines and cell phones.
- Free unlimited incoming calls.
- Always fits in your phone as it comes in standard, micro and nano formats.
Disadvantages
- 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. It needs to operate on dual-band or quad-band for that.
- You can’t recharge the SIM card when the 30 days have expired or the 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:
- Once you have received the SIM card, go to simcorner.com/registersim to pick a start date. The card will automatically be activated on that day.
- Disable mobile data on your phone while traveling to Switzerland if you don’t have a data plan from your home provider.
- 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.
- Enable roaming data on your phone.
- 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.
- Your phone number will be sent to you via SMS once the SIM card is active. You can also find it in your phone settings. This is the number people can call to reach your phone.
Option 3: mobile WiFi hotspot (recommended for groups who need a lot of data and can’t use an eSIM)
Before I used an eSIM, I rented a Travelers Wifi device for all my trips. It offered unlimited data and was often faster than the hotel’s WiFi. Travelers Wifi is no longer available but there are a lot of mobile hotspots that will do the job just fine if an eSIM is not an option for you.
Advantages of a mobile Wifi hotspot
- It’s fast. Most hotspots use a 4G network.
- You only need one hotspot for the whole family. You can connect multiple devices like phones, tablets, and laptops.
- It’s convenient. You do not need to replace the SIM card on your phone, or make any other changes to your phone. Your phone will continue to work as normal. Also, a hotspot is an excellent solution for locked devices that cannot use any other (e)SIM card. Even phones that don’t work in Europe can get online as long as they can connect to a WiFi network. A hotspot is a lightweight small device that easily fits in any pocket.
Disadvantages
- It is not the cheapest option.
- The battery usually lasts many hours. Nevertheless, I recommend turning it off if you don’t need your devices to be connected for a while. Charge it in your accommodation or on board a train: many trains have outlets. Make sure it’s fully charged when you leave for your day trips. If you expect to use it continuously and can’t recharge daily, I recommend ordering an extra rechargeable battery.
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. Note that Switzerland is not a member state of the EU. Many providers do count Switzerland as an 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.
