Data for Swiss trains and mountain towns
Switzerland is outside the EU and the EEA, so EU roaming rules do not apply there. Data use on your own plan is priced under your operator's terms, and the rates can be high. Check the terms before you travel, or buy an eSIM data plan at a fixed price.
The plan uses the Sunrise and Salt networks. In Zurich, Geneva, Lucerne and other towns coverage is usually good. In Alpine villages, on mountain roads and in long railway tunnels the connection can weaken or drop, so download maps and train tickets for offline use.
There is a lot to use data for: the SBB app handles train tickets and timetables, and Google Maps shows routes in towns and mountain villages.
The plan works only on Swiss networks, not in neighbouring countries. Near the border, for example in Basel and Geneva, your phone may latch on to a neighbouring country's network, and then the eSIM gives no connection. Your own SIM stays in the phone, but turn its data roaming off so that data goes through the eSIM. Save your SBB tickets to the phone before you enter the tunnels.

FAQ: Switzerland
Will the Swiss eSIM work in Germany or France if I cross the border?
No, the plan works only on Swiss networks. Near the border your phone may pick up a neighbouring network, and then the eSIM gives no connection.
Is there a signal in the Swiss Alps and on trains?
In towns and along most routes yes, but in Alpine villages and long tunnels the connection can drop. Save maps and tickets beforehand.
What can I use this eSIM for?
The plan is meant for mobile internet on your trip, for example maps, messages and browsing.
Will my own number still work?
Yes. Your own number and SIM card stay active for calls and messages. Choose the Reissaa eSIM for mobile data.
When should I buy the plan?
Buy and install the eSIM before you leave, while you have a stable internet connection.
Will my own mobile plan work in Switzerland?
EU roaming rules do not apply in Switzerland, and data on your own plan can be expensive. With an eSIM you know the price in advance.

Usually not. The sockets in Switzerland are type C, J, and a European C/F plug fits most of them. Voltage is 230 V.
