I have a new mobile number. How and where can I provide this or update my old number?

If you have access to a phone with your old mobile number:

1. Open the one App.
2. Go to Settings and update your mobile number there.

If you no longer have access to a phone with your old mobile number:

1. Log in to one-digitalservice.ch using your email address and password.
2. Click on “Reset account” and request a reactivation code.
3. Once you receive the code by mail, log in again and enter the code to reactivate your account.
