Buy a Swisscom Prepaid SIM in a Swisscom Shop and request number porting at the same time. Please present a valid identification card (ID card, passport or residence permit) for the statutory registration.
Notify your existing provider via text message that the phone number is going to be transferred. To do so, send a free text message with YES to 499 using your existing SIM. This SMS command is the same for all providers and is required for transferring the number.
You will then be informed via text message when porting has been completed. Porting a phone number takes at least 6 working days. Once the phone number has been transferred successfully, you can replace your previous SIM with your Swisscom SIM.
Please note that any remaining credit on the old SIM will expire after porting. Only remaining credit from M-Budget Mobile can be transferred.
Swisscom aims to be one of Switzerland's most sustainable companies. Our environmental and social commitments are therefore an integral part of our corporate strategy.
