AI Summary
Based on 5 community reports
Callers from this London number are impersonating O2, the mobile network provider. Reports consistently describe someone claiming to be from O2 and using a particularly deceptive tactic — telling people they need to send a new SIM card due to a system change. After gaining your trust during the conversation, the caller then asks for a £1 payment and requests your bank details. This is a classic scam setup, using a small, seemingly harmless payment to extract your financial information. One recipient wisely refused to hand over their details. With a spam score of 94/100, this number should be treated as highly suspicious. Do not provide any bank details or personal information to this caller, and hang up if you receive this call.
