Said from Tesco. Said it was about 3g shut off. Would be sending new sim for 5g. Asked if I was account holder. I said no, she asked when could she speak with holder. I said best if I ring her and asked for her number at which point the line went quiet so I ended the call.

SCAM - pretending to be from o2, calling about new 5G sim. They sound very legit but they’re not. Don’t respond.

Supposed to be from Tesco? Regarding a 5g change over, had most details, couldn't spell the basic of names, etc, stated my phone sim would be switched off, within 48hrs, as sending a new 5G simcard, passed over to her security department, sounded like same person, different background noise, not asked for any payments, at that point in conversation, got her to ring again later, give me chance to do a few checks.

Reported caller: Chris
