  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • thespacedmonkey Jonny Harris 🇬🇧 (@thespacedmonkey) reported from Ealing, England

    Unbelievably bad customer service from @O2 . I was found no service when I live in London is expected and I would not be a booster and that a booster didn’t even exist. A quick google found the booster. Also pretty rude to me. Not happy after 9 years with them to get that.

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • budgie Lee 'Budgie' Barnett (@budgie) reported from Paddington, England

    @O2 Wasn’t a problem, as such. ‘Kit breaks’ is an ever present rule. Was mainly to let others know,, if they had problems and wondered what was going on.

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • tanfish38 Tanya Fisher (@tanfish38) reported from Chesham Bois, England

    3rd day with no signal @O2 🤬

  • MissPaulaGreen Paula (@MissPaulaGreen) reported from Camden Town, England

    @O2 I have noticed that the WiFi is not working in 2 locations today 👀🤨

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • rafthemaster Richard Frame (@rafthemaster) reported from Kensington, England

    @O2 this phone number is harassing me - 020 3389 6395 - it’s a fake automated call claiming to be @HMRCgovuk called me 4 times already today! Wants to press option for operator (but I haven’t done so), needs reporting for harassment / impersonation of government service! @Ofcom

  • davidchow David Chow 📶 (@davidchow) reported from Hammersmith, England

    @MIROFUR Disagree. In the UK it was an exclusive on @O2 as they built out EDGE and turned on support for interactive voicemail. It created a massive influx of people to the base, who continued to stay on even when the 3G version eventually shipped to other carriers.

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • MabdiNur1 Mohamed Abdinur (@MabdiNur1) reported from Hammersmith, England

    @O2 I’m considering to leave after many years with you due to poor connection both voice and data. Shame once u was my no 1 choice of network.

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

    @O2 what is going on! 😭😭 Even when I have signal it's so slow!

  • Astr0Isha Astro Gyal 💦 (@Astr0Isha) reported from Brentford, England

    @O2 is down again ugh tell me something I don’t know

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • depeare Steve Depeare (@depeare) reported from Ealing, England

  • Steltek Michel Meyers (@Steltek) reported

    @O2 What do I do when a customer of yours enters my e-mail address as theirs and I get 11 e-mails from you regarding an account that is not mine? Your live chat is asking me to verify my birth date and billing address. I'm not a customer of yours, how am I supposed to do that?!

  • Louperb Lou (@Louperb) reported

    Hi @O2 how can i contact you about my phone contract? Been all through the app but can’t find the help I’m looking for.

  • giuseppecorate1 Giuseppe (@giuseppecorate1) reported

    @O2 hi what's going on with 5g in E7 9DZ postcode? I can hardly get an H as speed. No Internet on my phone and it's been bad for few days.

  • UKtodayUK the Real Mike 🧊 (@UKtodayUK) reported

    When the lockdown started I had nofurlough and no income for 8-weeks, everybody I have direct debits with etc helped me while I sorted my money out, that is everybody was helpful except for @O2 who said on their website they would help but you could not get thru to them.

  • SarahDi82698246 Sarah Dickson (@SarahDi82698246) reported

    @ZarinsAndrew @virginmedia @O2 Thank you for the updates! The chap I spoke to yesterday promised to phone back with a resolution but I've heard nothing since, will chase up tomorrow.

  • ahc72 Tony Coleman (@ahc72) reported

    @AXS_UK @axs @O2 Could some one please confirm the position as no responses to the messages yesterday. This is an issue when you wont take calls

  • sarah_robbo Sarah Robertson (@sarah_robbo) reported

    Didn’t think moving to @O2 would mean I had WORSE coverage than EE, only been back a week and fed up of data not working. Reconsidering things right now.

  • ThomasEdmund71 Tom Richardson (@ThomasEdmund71) reported

    @O2 ordered an iPhone 13 max pro. Your website said in stock. now I get an email saying it’s out of stock but no further info on when I’d expect it to be available. Your “contact us” on your web page is useless. No one available! How can I find out when it’s going to arrive? HELP

  • Caina07Adam Adam (@Caina07Adam) reported from Wychbold, England

    @O2 trying to book a ticket for a local oden with the voucher you’re offering for Monday but it’s not working????
