Have you paid your bill and are you still blocked? Wait for the next 48 hours.

Hello @Toncho ,

welcome to the o2 Community .

If you described your issue a bit more, maybe we can help you with it. If Bumer is correct with his assumption that your contract is currently barred from service for missed payments, than this is an automatic process and it will be unlocked within 48 hours of the payment being made.

Kind regards, Sven
