Important for the call number transfer:

• Termination:
  It's good to know that you don't have to cancel your contract with your current mobile provider. We take care of that for you! If you want to switch, it is therefore important that you do not cancel your contract with your current mobile provider. The application for the number transfer/cancellation does not begin with your cancellation, but with the completed registration with us.

• Termination period:
  In principle, you can leave your current mobile service provider even before the subscription contract expires (early contract termination). However, the current mobile operator may charge you a penalty fee for not complying with the terms of the contract. Therefore, check in advance which contract terms you have. If you are not sure, we recommend that you select the "End of contract period" cancellation type.

• Prepaid phone numbers:
  After registering with us, please confirm the porting by sending an SMS with the number to be ported to the number 499 with the content "YES". You can send this SMS even if there is no credit left on your prepaid card. If you are not able to send the SMS, you can contact your current mobile operator. They can also perform the deregistration for you manually.

• Swiss phone numbers / landline numbers:
  Please note that we can only transfer Swiss numbers from Swiss mobile operators to us. Foreign & landline numbers can unfortunately not be transferred to us.
