mark (@PieFaceMark) reported from London Colney, 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

Addictive Colors (@AddictiveColors) reported from London Colney, England@O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

-
Squall Loire (@squall_loire) reported@O2 No, because I don't answer calls I'm not expecting. If I wanted to discuss a complaint on the phone, I would call you. Written complaints should be responded to in writing, otherwise it feels like you're dodging anything being on the record.
-
Hugo Michiels (@hugomichaels) reportedYou know @O2 ,Ever since your network upgrade a few weeks ago in the Brighton area my signal has been far worse than it’s ever been. Should gave left it alone as it was working before. #itwasnotbroken #nothappy
-
Ruxanda Josan (@ruxjosan) reported@albieamankona Some UK operators might choose to apply this principle anyway. At least that's what @O2 customer service told me.
-
🇬🇧 Andy🇬🇧 (@4peterborough) reported@O2 your customer service is shocking refusing someone a 14 day change of mind we make a complaint you call back with a deal and said you will get another quote the escalations team yeah, right I'm still f waiting you're a joke.

-
rich ryan (@silly_balls) reported@o2 why has your app got so terrible. Apple Pay now times out and does not work, the save card option does not save the card. Why fix something that wasn’t broken?
