    @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 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?

    @O2 I’m trying to make an insurance claim and I keep getting an error message 401 unauthorised. Can you help?

    @SteveJoyce14 @O2 Generally there are issues with signal when there are large crowds of people gathering so close to each other I take it as a given that that's the case with music festivals, sports grounds etc so don't expect it when I'm in/around them

    @O2 My Daughters phone broke and o2 have been messing her about for 3 weeks now. Can someone please DM me so I can try and get this sorted ? Customer service has been awful, £80 a month to be treated so badly absolutely disgusting service.

    @O2 why is your coverage so poor at Potternewton Park Leeds LS7 4HA. In fact is poor in at postcode LS7 3LZ. If you get 2 bars of 5G. In fact in a lot of cases I get E. Who can forget the Edge network. You have the Leeds West Indian Carnival up. What should be a day of sharing content you don’t get anything. I suppose a temporary mast which Leeds Festival gets from all the networks we don’t qualify.

    @O2 can you sort your app and website out! Won’t let me look at my upgrade and won’t allow me to chat to an advisor online! Looking like I might have to change network provider.

    @virginmedia @O2 I can only assume the reason I’m getting an IDF-12B error is because I’m now using a Sky connection rather than a Virgin one. Same computer, no VPN… Trying to get into my O2 account btw… which support line do I contact?

    Whyvhave you closed my complaint when it hasn't been resolved? @O2

    Looking for resolution from @O2 been having ongoing signal and network problems since joining in December 2025. Live in EN1, Enfield. Complaint after complaint and still no resolution. Why pay for a service if we are not receiving it. Can’t make basic calls in our own home!

    @SteveJoyce14 @O2 @TheGillsFC I'm on O2 and the signal in Gillingham is shocking
