Expert Opinion

Earlier this week, a wave of calls claiming to be from O2 left many feeling pressured to upgrade or verify details. Callers typically warn that your SIM will stop working unless you act, offer unrealistic discounts, and use heavy accents or scripted speech. Never share personal or account information over the phone unless you have initiated the call and can confirm the number independently. Block the number on your handset and consider adding it to an official call‑blocking service. Report the incident to Ofcom or the Information Commissioner’s Office, and remind friends that legitimate providers will never demand urgent action via unsolicited calls.
