Expert Opinion
Verify your mobile provider's contact details before engaging with unsolicited calls claiming issues. These interactions often involve scammers impersonating Three, pushing for verification codes or access to personal accounts like emails. Hang up immediately if pressured for sensitive information; legitimate companies never demand remote access over the phone. Block the number and report to Action Fraud to curb further nuisance. Watch for patterns like repeated missed calls leading to callbacks—scam indicators include urgency about SIM blocks or device problems. Stay vigilant to protect your data.
