3 monthsI keep getting calls from someone saying they're from O2, telling me my phone is going to be blocked and a new SIM card will be sent the next day. It’s total rubbish, don’t fall for it. This is the fourth time they’ve tried this on me. O2 told me to just ignore and hang up. Definitely a scam!O24 monthsI got a call from a woman who said my SIM card was about to stop working and I needed to upgrade it. I told her I thought she was trying to scam me, but she denied it and just kept pestering me.4 monthsI got a call from a woman claiming to be from O2, saying something about my SIM card and a £26 monthly charge. I told her I wasn’t even an O2 customer and called her out as a scammer. She quickly ended the call. Complete waste of time and really irritating!5 monthsSomeone rang me pretending they were from Tesco Mobile, asking for details about my account. It's strange because I always get everything they need to tell me through emails or letters.Tesco Mobile5 monthsGot a call from someone trying to scam me into updating my sim-only plan, threatening it’d get blocked if I didn’t comply. Told the person I’d hold off until I spoke with my actual mobile provider first.5 monthsSomebody said they were ringing from O2 to check how my network reception was. I mentioned that I keep getting loads of scam calls, so I asked if they could give me a proper O2 contact number to ring back on. At first, they were pretty reluctant to share a number, but after a bit of pushing, they finally did. The number was 02039961489, which I later looked up here and it seems dodgy too.5 monthsThe guy on the phone had a weird accent that I could barely get, but he kept going on about my SIM card being blocked or something. I just told him to get lost and hung up straight away.5 monthsI keep getting tons of calls from this same Vodafone number, but I never pick up. Looks like another scam attempt or some kind of fraud going on.Vodafone5 monthsGot a call from this number but didn't pick up. Lately, I've been getting calls from numbers like this one, mainly early in the morning.5 monthsThere was this scammer who used Google voicemail to get me to say my name and record my voice. It felt really off and shady.Google5 monthsHad a really hard time catching what the woman was saying, her accent was quite strong and she was talking super quick. After a while she claimed to be from O2 and said I’d already paid for my SIM through them. I told her I’d handle my SIM stuff through my provider’s app myself and then ended the call. Been using the same network for years, which actually runs on O2’s network, but never got a call like that before. Definitely felt a bit dodgy.O25 monthsI didn’t pick up the call. They rang again right after the first one. The ID showed it was from London. Heard loads of folks say it’s a scam. I’ve blocked the number now and plan to report it to the official scam hotline.London5 monthsTotal scam. They claimed to be with O2, saying they knew I was a customer because I supposedly have a contract with them. When I asked for my name to confirm they were legit, the lady said she’d only reveal it once I’d confirmed my security info. But I don’t even have an O2 account! Needless to say, I blocked the number straight away.5 monthsThey called me up asking questions about my mobile phone plan, said it was some kind of survey.6 monthsI found this scammer lady quite daft, but honestly, it was pretty funny to deal with her!6 monthsSomeone rang me saying they were from O2, which is who I’ve got for my phone.

Then she checked if I wanted to keep my existing number and asked if I’d be in to receive the SIM the following day. When I suggested they could just drop it through the letterbox, she kept pushing about me being home to take it. I ended the call after that, so no idea what kind of personal details they might have tried to get from me.6 monthsGot a call from someone saying they were with o2, telling me my number would be cut off in the next day. I didn't even let them explain what I was meant to do to stop it.
