Change of number with Prepaid


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.


Reminder service

Notice period

We will remind you to notify your present provider about porting your number in good time before the notice period expires. You can also apply for porting directly online or in any Swisscom Shop.
