    @O2 ever since I switched from a 4G SIM to a 5G SIM, my signal is shocking at home. I don't have 5G in my area and even when I turn 5G off, I'm only getting one bar of signal, calls constantly drop. Can I switch back to a 4G SIM? #Help

  • helan_bunker Helan bunker (@helan_bunker) reported

    Shocking signal lately from @O2 yet they say there’s no problem. We have had emergency calls only and we’re not the only ones in the area either

  • Blondie1901 Loz (@Blondie1901) reported

    @O2 really really frustrated and angry! Got a message to say my airtime was overdue and would be charged late payment - I have not changed any details or my bank account so why isn't it working? When I try to access help online the webpage goes blank! What is going on?! #help!

  • Fire_Cafc Danny Blackwell (@Fire_Cafc) reported

    @AbcdSarah @O2 I’ve had no signal for 4 days on my phone . They’ve said it’s a mast issue by mine but it’s not working anywhere I go with it

  • RodStevens17 Rod Stevens (@RodStevens17) reported

    @O2 hey guys how do I speak to a person that can help with my account without having to wait for over 30mins on the phone? Cheers

  • upies1862 morphpie (@upies1862) reported

    @O2 Is there an issue with the website? I can view the store but when I sign in all I get is a blank page. Happens on pc, mac & ipad

  • ticktockreed Tim Reed (@ticktockreed) reported

    @O2 I'm unable to log into my account on any device in any browser. The connection times out every time. This is extremely frustrating. Please help

  • itsnadine_ abena (@itsnadine_) reported

    @O2 No it just never works this has been going on for years, your price keeps increasing and there are no improvements. This is woeful and your customer service is ridiculous. Your competitors are miles ahead of you, it’s a real shame because you can’t even manage a quality service.

  • Clauds84 Claudia (@Clauds84) reported

    @O2 I was misled by o2 customer service shop- told to pay off device to upgrade and you don’t sell 12pro max anymore, was asked for id and passwords. Wasn’t given 5G SIM card please contact me as I have paid alot of money when I shouldn’t have had to
