Try your sim in another phone in case it has failed.
Any O2 shop with give you a new sim for free.
Also check for local network issues here O2 Service Status
Generic network help here Guide: Is the network down for me or everyone?
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
