AI Summary
Based on 3 community reports
This London number is impersonating Vodafone in what appears to be a SIM deactivation scam. Callers claim to be from Vodafone and warn that your SIM card is being deactivated, likely attempting to trick you into providing personal details or payment information to "reactivate" your service.
This is a common scam tactic where fraudsters create urgency by threatening service interruption. Legitimate mobile networks will never contact you out of the blue about SIM deactivation without prior communication through official channels. The reports are consistent in describing the same Vodafone impersonation, though they lack community voting to gauge reliability.
If you receive this call, hang up immediately and contact Vodafone directly using the number on your bill or their official website to verify any account issues.
