    @O2 Network reset? Not sure what that is... Not in London often and last two times when I try to connect to wifi extra it requires login info, multiple locations across the tube network. I've searched for a solution and doesn't seem to be any options.

  • NeilHigley Neil Higley (@NeilHigley) reported from Royal Kensington and Chelsea, England

    @O2 your 4G is worse than a late 90’s dial up, when it works of course. As you are consistently failing to provide…well any service what so ever, I can break my contract no questions ask and go back to @EE that I wish I’d never left?

  • juliet_gough Juliet MacKenzie Gough (@juliet_gough) reported from London, England

    @O2 hello. I have just moved over to O2 and am considering buying a phone from the company Oneplus. I have read that Oneplus phones don't work with the O2 5g network, is this correct? I don't want to buy the phone then realise I can't receive 5g. Thanks in advance

  • dazp1919 Darren Pammenter #COYS (@dazp1919) reported

    @O2 is the network down? I can’t ring out or recieve calls.

  • CandiceVigario Absolutcandy (@CandiceVigario) reported

    @O2 It would be a great summer abroad if the data I paid for was provided to me! Customer service is poor, the app merged with Virgin is slow and unreliable and there is no breakdown of data usage. My data due disappeared on the renewal date and customer service can’t explain it!
