2G network
The GSM (2G) network will soon be switched off in Switzerland. Sunrise is switching off the network at the end of 2018, Swisscom and Salt are to follow in approx. 2020. This also applies to all respective providers (Yallo, CoopMobile, M-Budget Mobile, Wingo etc.)
We therefore recommend selecting «3G» in the filter. This way you can be sure that your device has 3G and you can use the Swiss network without any problems in the future.
