    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 I've bought a Galaxy watch 5 pro. Had staff in-store set it up, it doesn't work. I've noticed their is no eSIM for it in the SIM manager should it show up their? Fairly sure that's why it's incapable of making/receiving calls&texts 😑

    @Nonhappyclapper @O2 US roaming is covered in my O2 contract - network speeds could be better when roaming in the US but that’s not an O2 issue at all

  • jadesharp1992 Jade Sharp (@jadesharp1992) reported

    @O2 people if they are having problems should get a service they deserve and should be able to receive updates?

  • DanielAleks92 Daniel Aleksandrowicz (@DanielAleks92) reported

    @O2 Hi. Did you had any issues yesterday, around 5pm at Edinburgh (EH9). Because I tried to watch football at my phone and I couldn't because of slow speeds.

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @mrtnwith @O2 @mrtnwith same here I might do that as well stop my direct debits if you can’t speak to customer services.

  • KevinCrossCM Kevin Cross CM (@KevinCrossCM) reported

    @O2 No. I am just cut off every time. When I call and ask to *make a complaint* the system just hangs up on me. Wow! My patience, which you apparently appreciate, has expired.
