AI Summary
Based on 1 community report
This UK mobile number (carried by O2) has been flagged for a scam call. A single user report describes a delivery-scam line asking for bank details, then a second call from what sounded like a Virgin Media representative. The caller spoke from a script, and the person had no VM account, which is a red flag. With a spam score of 80/100, it’s considered high risk, though there are no upvotes to confirm. Tactics include pressure to share banking information and impersonation of a well-known company. If you get a call like this, hang up immediately, do not share bank details, block the number, and report it to your provider or Action Fraud.

Shortly after being asked to provide bank details by a deliver scam caller, I received a further call from this number which seemed to be from the same area code as mine, so I answered it, and was spoken to be someone claiming to be from virgin media. I have no account with VM and no reason for receiving a call. The caller was clearly reading from a script similar to other scam calls, so I ended the call.

Safety score
1 reportHow this score was worked out
Each report rates the number as safe, unknown, suspicious or spam. The score combines those ratings, giving more weight to clear scams, and each person counts once. A number only reaches high risk once several people have independently reported it. Scores of 70% and above count as high risk, 40% to 69% as medium, and below 40% as low; a low-risk number reads Maybe Safe once someone reports it as safe. More about spam scores
