Any prepaid card you buy in Switzerland can give you the opportunity to keep a swiss number and call and receive calls from your friends in Switzerland.

I would however check the roaming charges for incoming and outgoing calls and texts charged by the swiss operators. Switzerland is not part of the EU and therefore operators may still charge differently when you are using your swiss number in Germany.

If you do not want to use the data feature, just do not book a data package and switch off data on your mobile phone.
