Can I make calls and surf abroad with a foreign SIM subscription card and have a Swiss SIM card in the device at the same time without automatically using the device via the Swiss card and thus incurring high costs?

Accepted Answer

Yes, that is possible. You can switch the SIM cards on and off separately. It is also possible to specify which SIM card is used as the default for data, SMS and telephony. When I'm abroad, I always deactivate my Swiss SIM and only use the foreign one.
