I have recieved several calls from an 0121 number, Simon from 3 apparently, saying I need a new sim as there is a technical/network issue, and I have 3 days until it's no longer usable so they'll need to send me a new one. I told him I couldn't talk to him as at work, he sent me a WhatsApp message with his number asking me to call him. I haven't and he's just rung several timss again. Sounds like a scam? Anyone had anything similar? Thanks.
