Edit your phone number in settings.
Turn phone off and on again.
Then it should work.

Settings. Phone. My number and edit to the correct one you want to use.
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.

Thank you managed to do it finally! I'd tried to do it in Settings but finally seemed to sort itself out after a restart. Thanks for you replies
