Switzerland has the finest pistes in Europe and, at the same time, the most annoying telecom situation: the country is not in the EU, not in the EEA, and therefore outside roam like at home. Your home bundle ends at Basel. People who do not know that usually find out through the invoice.
This February the Swiss Alps are busier than usual, because Crans-Montana hosts the Alpine World Ski Championships from 1 to 14 February. All the more reason to sort your data in advance.
Why your bundle does not work there
Roam like at home covers the EU plus Norway, Iceland and Liechtenstein. Switzerland is not on that list. Some providers bill Switzerland at EU rates as a courtesy, but that is goodwill rather than a right, and it varies per plan. Check your own terms before you leave rather than assuming.
What you miss without data on a ski trip is exactly the useful stuff:
- Lift status and piste reports. Which lift is running, which run is open, what has been groomed.
- Weather and avalanche warnings. Above the tree line the weather changes faster than the forecast did.
- Finding your group again. Everyone skis at their own pace, and "at the hut at one" rarely survives the morning.
- Ski tracking apps. They count your vertical metres and share your route, and all of that uses data.
- The rail app. For trains and postbuses back down the valley.
The trap most people do not see coming
You do not even have to ski in Switzerland to end up on a Swiss network. In border areas your phone grabs the strongest mast, not the cheapest one:
- In Zermatt you can easily land on an Italian mast, and in the Italian resorts next door it happens the other way around.
- Driving to Italy takes you through the Gotthard, and between Basel and Chiasso you are in Switzerland for hours.
- In French and Austrian resorts close to the border, a Swiss operator sometimes shows up in your network list.
If you ski in France or Austria, set network selection to manual and pick a local operator. And if you drive through Switzerland to Italy, count on being outside your bundle all day.
How much data do you need on a ski trip?
| Type of trip | Estimated usage |
|---|---|
| Long weekend (3-4 days) | 2-4 GB |
| A week of skiing | 4-8 GB |
| A week with lots of photos, video and tracking | 8-12 GB |
Your hotel has wifi, so the heavy uploads happen in the evening. During the day it is maps, messages and weather updates, which add up more slowly than you would think. Not sure? The data calculator will check for you.
Practical: cold and your battery
In the cold your battery drains faster, and a dead phone is more of a problem on a mountain than at home. A few things that help:
- Keep your phone in an inside pocket, not an outer jacket pocket.
- Download the resort map offline so you are not reloading it all day.
- Put a small power bank in your backpack.
- Set your travel eSIM as the data line and use your own SIM only for calls. That way your home plan never uses data at roaming rates.
How it works
- Order your bundle. Pick an eSIM for Switzerland for the length of your trip.
- Scan the QR code at home, on your own wifi. Do it before you leave, not in the car.
- Switch on data roaming for your eSIM once you cross the border, and switch it off for your own SIM.
Frequently asked questions
I am only driving through Switzerland to Italy. Do I need anything? If you want to navigate or stream on the way: yes. A small bundle is cheaper than a few hours of roaming outside your plan.
Does my eSIM work in Liechtenstein too? Liechtenstein is in the EEA, so it falls under your own bundle. Useful detail: it partly uses Swiss networks, so check which network you are on.
Will I have coverage on the slopes? In Swiss resorts coverage is excellent, right up into the gondolas. In deep valleys and behind a ridge it can drop out.
Can I make calls with the eSIM? Our bundles are data-only. You call over WhatsApp or through your own SIM. Note that calling on your own plan in Switzerland does fall under non-EU rates.
Conclusion
Switzerland is the most expensive place in Europe to roam by accident, and you do not even have to holiday there to end up doing it. Sort a bundle before you leave, set network selection to manual if you ski near the border, and enjoy the pistes without thinking about your bill.
