    @O2 I just had a call from 01204204019 claiming to be you, with a great offer on my O2 sim. I suggested he should try cyanide gas instead of O2, and he swore at me and hung up. Some people are so rude.

  • iamSabrinaAnne Sabrina-Anne (@iamSabrinaAnne) reported

    @O2 oh no I think I just made a long international call by mistake. I thought I was using FaceTime audio. Is there anything I can do to avoid the charges? Pls help… the rates are insane 😭😭😭

  • Kalrell Kalrell (@Kalrell) reported

    This isn't helped by @O2 4g signal failing to provide Internet right now. Had to force the phone to connect only to 3g for these tweets. 😠

  • therenfrewferry Renfrew Ferry (@therenfrewferry) reported

    @O2 Hi big having probs today literally no signal in Glasgow G3 8QQ area now in PA4 8SA phone signal keeps disappearing then coming back. 4G totally down. Message keeps popping up “O2 has switched off 4G calls on your account” any updates?

    Hi @O2 there’s no or very poor signal in most of the CA17 postcode - do we know when it might be restored please?

  • JohnnyTortoise Becky Hamblin (@JohnnyTortoise) reported

    @Gismo_the_Rogue @virginmedia @O2 It would be helpful if Virgin used their account to keep punters updated when their lack of service impacts large areas.

  • richpars Richard Parslow (@richpars) reported

    @virginmedia @O2 Did your TV service just fall over (Berkshire area)?
