You also use your mobile phone number in a permanently installed car phone, for example, and do not want to switch the SIM card constantly.
Unser Angebot
The additional SIM card from Swisscom saves you the trouble of constantly switching the SIM card from phone to phone. However, simultaneous use of the two cards is not possible. You can set up a different service configuration for the main SIM card and additional SIM card. As a result, you can forward unanswered calls on your car phone to your secretary, and activate the COMBOX® on your mobile phone, for example. Monthly costs: CHF 10.
