    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

  • AmeliaElton Emily Kay - Writer (@AmeliaElton) reported

    @O2 my partner took out a phone contact with you a few months ago and barely has had any signal unless he is at home connected to the WiFi. This is ridiculous, the phone is just a glorified calculator unless on WiFi. Should have stayed with EE.

  • WheatoMan Mark Partridge (@WheatoMan) reported

    @pmdv77 @EnglandRugby @O2 He's been very good every other game I've seen him and apart from a charge down I don't think he was to bad. The replay of the early knock on showed he didn't actually touch it and the ball wasn't out when he got caught after that.The intercept was just a poorly planned move imo

  • AdzCrawford2003 Adam Crawford (@AdzCrawford2003) reported

    @O2 If you actually tweeted that from your phone, you would have one of the following issues… 1. Congestion in the area, 2. Lack of signal. Lol

  • TariyePeterside 💖 Tariyé 💖 (@TariyePeterside) reported

    @O2 what is wrong with your network today? I can barely make any calls and the one I managed got disconnected right when I was about to make progress

  • sjmjarvis Sarah JM Jarvis (@sjmjarvis) reported

    @O2 Hi @O2. I have cancelled it now. I think perhaps this was part of the problem but the instructions really aren’t clear. I think the free period ran out either Sat or Sun. Just hoping I don’t get charged as cancelled this morning!

  • AndrewDrisc Andrew Driscoll (@AndrewDrisc) reported

    @O2 Yeah it's rubbish when something it needlessly slow.

  • jarlanjoseph JarlanJoseph (@jarlanjoseph) reported

    @JUULESY @O2 Submit a formal complaint to o2 & threaten them with the @ICOnews if they don’t stop sharing customer information with the Govts ‘Situation Room’, also known as SitCen. They’ll say the data is ‘fully anonymised’, but how do customers know that for certain.
