If someone calls you claiming to be from O2, make sure you check who they are by asking where they’re calling from. Remember, we’d never call you and ask for one-time passcodes, passwords, PINs or personal information like your bank details. If you have any doubts, call us on 202 (free from your O2 mobile) or on 0344 809 0202 (standard UK rates apply).

If you've been a victim of fraud report it straight away.
