  • AddictiveColors 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

  • JoeAchilles Joeachilles.com (@JoeAchilles) reported from Denham, England

    Mother has been getting scammed by a mobile app service "Lasevia limited" for past 8 ish months, her mobile provider @O2 can't help at all. Looking online this has been an issue for ages yet nothing has been done by O2 😡

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • marcwhufc marc foley ⚒ (@marcwhufc) reported from Barnet, England

    @o2 your service has been shocking nearly 2 weeks and my daughters Apple Watch for Xmas not here. Now by all accounts best to start the order again as will be quicker and wait a week for deposit to be put back in my account 🤬 look at your dm’s I’m in them 2 replies so far 🙄

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

    @BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Walthamstow, England

    @O2 Please don’t tell me this mast is still not fixed. Again sat at Liverpool Streets Station with full service and 4G and nothing happening on phone full stop. Time to accept that coverage here is not good enough.

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • marcwhufc marc foley ⚒ (@marcwhufc) reported from Barnet, England

    @sally290718 @O2 @02 I’m phoning them back tomorrow and doing that shit service though xx
