    @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.

  • 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?

    @O2 O2 app - click Support - then scroll down the the faq using your phone abroad. Sounds like o2 have either made a bit of a blunder in advertising a change in terms or are intentionally misleading

  • __Saran__ Saran (@__Saran__) reported

    @O2 Added a bolt on by texting 21500 & was sent confirmation that my request had been received & would be processed within 24hrs. It's been over 24hrs, MyO2 shows the option to add but takes me to a 404 page when trying. Help line hung up on me & online chat not connecting.

  • DanielJSims Daniel J Sims (@DanielJSims) reported

    @O2 For about 4 years or so I think. Service improves when I leave my estate.

  • maberesford Mark Beresford (@maberesford) reported

    @O2 Yes I went into the help tab and then clicked on using my phone abroad

  • wxmsmith Llanelwy Reds (@wxmsmith) reported

    @O2 I’m trying to upgrade my phone on my app and PC but nothing working. Are you having trouble on the website? @o2

  • chazzerhart Superman KOTW (@chazzerhart) reported

    I’m dumping @O2 as humanly possible, no signal all game as usual at the match

  • McBobington Rob McLaren (@McBobington) reported

    @O2 Really appreciate your help. I’m hotspotting from my wife’s phone (on 3)…. Boom! Instant connectivity. I’ve been with O2 for years and it’s worse now than when we didn’t have 4G.

  • fingers_ginger ginger.fingers (@fingers_ginger) reported

    @sophr136 @O2 This is her if you can DM as soon as please. Customer service have been tried hbut they are difficult to understand and didn’t care because it wasn’t the ‘correct’ department

  • HardCand Zack (@HardCand) reported

    Thank god @O2 's 5g in roaming is enough to cover my internet use because @virginmedia broadband package I pay for is always down, and I get no help except "You should post on the forums" even though their engineer said it's a faulty VM installation... welcome to 2021

  • ChrisEddy_7 Eddy 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@ChrisEddy_7) reported

    @mikejt67 I’m thinking of changing over to Sky Mobile myself as @O2 have broken masts in my area they still haven’t fixed for over two years ans I can’t get any signal to load data etc I’m just worried what masts they would use? Lol
