02037278535 rang me earlier, but my phone marked it as potential scam, so I ignored it. I’ve blocked the number now, but it’s pointless since they just ring from another one. My landline gets about eight calls daily from similar numbers, but I can't block them because the phone doesn’t have that feature. It’s really annoying. Be careful, these callers are nasty and you can’t trust them!

Got three calls within a few hours, all saying they were from O2 or Tesco Mobile about some ‘system upgrade’ and that I needed to get a new SIM card. Definitely felt like a scam to me.

I got a ring in the afternoon on a random Thursday, right in the middle of my work hours, which seemed odd. I decided not to answer since the number wasn’t saved in my phone. Now I’m pretty certain it was some sort of scam call.

The number seemed a bit dodgy, so I didn’t pick up. Decided to have a quick look here before I went ahead and blocked it.

Got a call from someone warning me that my SIM card was about to get blocked. I kept quiet the whole time, knowing it was probably a scam. She tried to trick me by asking who my network provider was, rattling off a bunch of names to get me to confirm one - but I didn’t say a word. Then she started insisting my SIM would be blocked soon and tried to scare me. Pretty obvious scam, so I blocked their number straight away and decided to report it here. I’ve labelled it as dangerous because I’m sure anyone who falls for this could end up seriously losing money to these fraudsters!

My wife’s phone keeps ringing at least twice every day, and she never picks up. I always thought it might be some kind of scam, and after looking into it, this info pretty much proves it.

Got a call from someone claiming to be with O2, told me my SIM card was about to get blocked and that they'd send me a replacement. Thing is, I’ve never had a contract with O2, and it just doesn’t feel like how a proper company would reach out without warning. Pretty sure it was a scam.

I didn't have the number saved so the call was automatically muted. Since it was unfamiliar, figured it was suspicious and decided to block it.
