You need to contact customer service

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

Most likely a sim failure.

Pop in store with photo ID for a free replacement.
