You may need a new sim card,
Pop into your local O2 store with photo ID or call 0344 809 0202, 0800 902 0217 or 0800 032 1402
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.
