  • 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

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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • 5tuuuu Stu (@5tuuuu) reported

    @Nonhappyclapper @O2 US roaming is covered in my O2 contract - network speeds could be better when roaming in the US but that’s not an O2 issue at all

  • _red4g Richard (@_red4g) reported

    @O2 I've bought a Galaxy watch 5 pro. Had staff in-store set it up, it doesn't work. I've noticed their is no eSIM for it in the SIM manager should it show up their? Fairly sure that's why it's incapable of making/receiving calls&texts 😑

  • drlajama89 Lor (@drlajama89) reported

    @O2 Could I have signal in my own area in the UK before I start roaming please?

  • DanielAleks92 Daniel Aleksandrowicz (@DanielAleks92) reported

    @O2 Hi. Did you had any issues yesterday, around 5pm at Edinburgh (EH9). Because I tried to watch football at my phone and I couldn't because of slow speeds.

  • DrLochHartley Lochani Hartley (@DrLochHartley) reported

    @virginmedia @TheBHF @O2 Wow - looking at the majority of the tweets on here and from my experience with virgin service and poor poor poor Wi-Fi since early Dec…as a NHS doctor, I sincerely hope your define are more reliable than your company!

  • MartinD18377578 Monyeko (@MartinD18377578) reported

    @O2 Impossible to get through on your live chat and customer service line-

  • begbie86 jaysus lad (@begbie86) reported

    @O2 Your help and support is a joke. Honestly would never recommend anyone to join a network that makes it so difficult to use your services. My contract is over and trying to change it to pay as you go sim. Can't get through to customer service for 3 days now!!

  • PAUL_NAV7 Paul Navarro (@PAUL_NAV7) reported

    @O2 @o2 yet again another drop In network coverage in the area I work in and need my phone to work. Third time in 6 months it's disgusting service. As soon as u can I will be cancelling my contract.

  • Cheeky_monquay Iona McIntosh (@Cheeky_monquay) reported

    @O2 Hello O2, I sent a tweet on 3rd Feb saying that you need to review your service level agreements with DHL who have yet to deliver my order. This order was promised on 3/2 and DHL said they would deliver that day. Still no delivery? I'm now asked to review purchase?????

  • KevinCrossCM Kevin Cross CM (@KevinCrossCM) reported

    Without doubt, the company that has fallen the farthest is @O2. It is shocking how poor they have become. I am trying to get customer service to resolve an issue, but repeatedly am told there is no one who can talk to me.
