AI Summary
Based on 3 community reports
This Birmingham number has a high spam score and multiple reports describing unsolicited calls impersonating mobile network providers. Callers claim to be from companies like Three Mobile or Vodafone, using the tactic of warning that your SIM plan is ending or that your phone number is about to "run out" — a classic pressure tactic designed to panic you into engaging. One reporter noted the number called back repeatedly after they hung up, which is a common harassment tactic used by scammers. Being registered with TPS has not prevented contact either. No reports have votes, so confidence levels are uncertain, but the pattern across all three reports is consistent. Do not engage with these callers — your phone number cannot simply expire, and legitimate providers would contact you through official channels.
