It's not possible from o2 Postpaid to o2 Postpaid. 

Hello @rtartari and welcome to our o2 community :-)

As @Bollermann already stated we unfortunately do not offer a transfer of a phone number from one post paid contract to another. Maybe a contract extension with a tariff change would have been a possibility?

If the number is important and you need it on your contract the other possibility would be to first transfer to a prepaid operator first and the import it back to your new contract.

Regards,

Lars

Thank you Lars, the last one is the option I’m considering.

Best,

Hi @rtartari 

please make sure the first new prepaid provider where you want to “park” your number temporarily doesn’t belong to an o2 brand before you transfer it back to your contract.

In case you have further questions feel free to leave us a message here.

Best regards,

Michi
