AI Summary
Based on 6 community reports
This London number is being used for O2 impersonation scams, with callers claiming to be from the mobile network about account issues or special offers. Reports describe tactics like asking about monthly bills and offering "lower price" packages, which are classic signs of telecom fraud. One person was specifically told they could get their current package cheaper, while another received a call despite not even being an O2 customer.
The pattern of multiple calls in quick succession and the fact that people's scam detectors are flagging this number adds to the suspicious nature. These scammers often try to gather personal information or convince you to switch contracts through unauthorized third parties. If you receive a call from this number claiming to be O2, hang up immediately and contact O2 directly using the official number on your bill if you need to verify anything about your account.

Scam detector warned me, so I didn't pick up.
It was a London number, and as i don't know anyone there, it must be spam
Some guy called from O2 about my monthly bill, asking for quick feedback, then said I could get the same package at a lower price. I don’t handle my phone contract; it all goes through my dad, and from what others have said, I’d guess it’s a scam.
Called me two times in a row but I didn't pick up.
It's a number I don't recognise and seems unlikely to be a real call - maybe a misdial but feels suspicious.
