Is it possible to block a sim card on my contract

Blocking a sim card

[Cleoriff]

It Is @Matt10 

Usually when you haven't paid your bill, or its been reported as lost or stolen.

Either way, if yours is blocked, you need to contact O2 to find out why it's blocked.

All numbers are in this guide Guide: Coronavirus Community Help and Support 

0800 587 4005 is the best number to try.

Use Skype if you have no access to any other phone. In the guide above.
