    @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€

  • 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?

    @Extinguisherman @O2 The thing is they're not the cheapest option on the market so you expect a premium level of service

  • misswhiskygirl Danielle 🏳️‍⚧️ (@misswhiskygirl) reported from Stoke-on-Trent, England

    @O2 I've just tried on desktop and it's working there, it's not working via the priority app. Thank you

  • r_you_rosa Rosa (@r_you_rosa) reported

    16/08. I ring customer service. Guess what @O2? No one's escalated my ticket! And this time they tell me I have to wait another 3 to 5 working days for this to be resolved. YOU CANNOT MAKE THIS **** UP

  • _Fraz7 Fraz Ali (@_Fraz7) reported

    @AshScrivens @O2 @EE NO ******* WAY!! EE never O2 again!!

  • atomicape99 J D (@atomicape99) reported

    @Extinguisherman @O2 I have just sent it again slightly edited with the tags you sent. I live in a major city centre (literally yards from a 5G mast not sure if its O2) I hardly ever get 5G and when I get 4G it's shockingly slow. Don't get me started on the phone signal.

  • mit_wolf GRiZZLY (@mit_wolf) reported

    @O2 am getting intermitant and barely functioning signal on the North Norfolk coast. Been like this since 6pm yesterday. Hopefully you've got someone looking into this.

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @atomicape99 @O2 One thing they know how to do is charge for a crap service.

  • princessmel_87 𝕄 𝔼 𝕃 👑 (@princessmel_87) reported

    @O2 No unfortunately I don't leave my home (health reasons) so I just don't know why it suddenly only gives WiFi option to do the updates never happened last time

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @atomicape99 @O2 The t&c’s state they don’t guarantee a connect all the time, be nice most of the time though!! Using my location, service page says good 2,3,4G, but status page says masts get busy (better term than congested). So how do u deliver a good service on congested mast?
