We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

or give them a call on 202 or 0344 809 0202

Is this an upgrade via O2?

Chance they have swapped you to eSIM and turned off the old SIM

Check in My O2

@Leemusgrave1234

or if you're trying to use a new sim, revert back to your old one.
