Activate your SIP credentials in My Swisscom. You will then be able to set them up on a third-party SIP device or VoIP client.
Do you think someone is using your SIP credentials and making calls at your expense? Delete your SIP credentials immediately in My Swisscom(opens in new tab).
If you are giving away or selling a device that is set up with your SIP credentials, make sure you delete the SIP credentials beforehand. To do this, reset the device to the factory settings.
SIP credentials allow you to use your Swisscom fixed network number on third-party devices and VoIP clients, as well as Swisscom SIP telephones, anywhere in the world. Once the credentials are set up, calls will be charged to your fixed network subscription. The costs are identical to normal fixed network calls.
SIP credentials consist of user name, authentication name and password. Keep these details confidential so that nobody else can make calls at your expense.
Restart the Swisscom router.
To do this, set up the SIP credentials for the selected telephone number on the device. Automatic support for nomadic use ceased on 3 May 2021.
The costs are identical to normal fixed network calls. They are charged according to your fixed network subscription.
If you use a mobile app to make calls, you may have to pay additional roaming charges while abroad. In this case, we recommend that you buy a data package.
Go to the SIP credentials in My Swisscom(opens in new tab) and select “Update”.
