    @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.

    @O2 hi. My friend’s UK mob stolen in Dublin. Need to cancel/freeze fone account. Help!!

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

    @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€

    Oh the irony, @virginmedia still down & will b repaired by 10am tomorrow 🤥 So I figured I could use my @O2 data, however it seems every ****** is having 2 do that so the signal is ****

  • JoeiMini Jo Howard (@JoeiMini) reported

    Switched to @O2 2 months ago and cannot believe how absolutely rubbish my signal is now. Joke! Should never have left @ThreeUK

  • DJWMarathonMan David J Wright (@DJWMarathonMan) reported

    DPD UK are so rude unprofessional and never on time but thanks to @O2 they will feed back the poor service I had from DPD UK I just hope they don’t use DPD UK again

  • jowhite1 Jo White (@jowhite1) reported

    @O2 Hi, mine and my daughter's signal has suddenly, over the past day, lost service. We can't get any signal in our house, which we've had no problem with previously, meaning our phones are constantly emergency service only. Are you able to look into it?

  • JoanneCater Joanne Cater 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦 (@JoanneCater) reported

    @allza1903 @O2 Did it about 5 times and kept getting error messages back…. Finally managed to get hold of someone helpful @ o2… who knows what the problem was but at least I will have a working phone on Tuesday 👍🏻

  • JemmaLDS Jemma (@JemmaLDS) reported

    @O2 The problem isn’t that you didn’t answer ~ you did after 20 mins! The answer is you hung up on me with no call back.

  • Daniel237 Daniel Magee (@Daniel237) reported

    @O2 hi I’m traveling in the us and for some reason I can’t connect to a network. Is there an issue?

  • tm_gilman Tom (@tm_gilman) reported

    @O2 signal is appalling! Once you’re surrounded by 10 or more people it just doesn’t work. Football stadium? No chance mate. In the pub with friends? Dream on buddy

  • LittyMan Paul Lewis (@LittyMan) reported

    @o2. Your service in Central Bath Uk, is appalling. Limited data (4g) at the Bath Rugby match, won't even allow me to tweet about my favorite rugby team. Please don't reply with a 'sorry'. Getting fed up with excuses. Get it sorted instead. #poorcustomerservice #NoExcuses

  • NathFerguson Nath (@NathFerguson) reported

    @O2 why do you never respond to a formal complaint u get told your hear from us and for the second time I heard nothing your customer service is shocking
