O2 customers are being warned to be aware of certain malicious texts and phone calls.
Scammers who are trying to steal personal details by offering bogus “discounts” on your phone bill have been calling customers claiming that they could get up to 30% off. They then send you a text with a one-time passcode and ask that you read it back to them.
But O2 warned that you shouldn't do this and confirmed that it is a scam. The company said that they would never ask you to read back a one-time passcode, reported The Mirror.
