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

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

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

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

  • 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!

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

  • aktyrrell Andy Tyrrell (@aktyrrell) reported from Walthamstow, England

    @harwood_steve @O2 @EE EE service is shit around Chingford guys I work with never get a service I'm o2 never had a problem. Probably the country you're in. Plus we always get upgraded at the o2 by the o2 Angel's.

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • 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!

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • stourdave Dave (@stourdave) reported from Tottenham, England

    @O2 Yes #stop please **** off with this shit. I only accidentally liked your ad while I was scrolling and you've bombarded me ever since. Your signal is shit anyway.

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    @LuzDLuna @O2 When I got to the shop to collect the phone and was denied, since a driving license valid across Europe wasn't good enough, I was told the "there are procedures and cameras" and the staff couldn't help because they would get in trouble!

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @Armaanilyas2 @O2 It’s so crap!

  • helenrigbyphoto Helen Rigby (@helenrigbyphoto) reported

    @O2 @lec246 Hi, any update on this? My mum’s upgrade was done Friday morning & she’s had no phone service since... I’m hoping you’ll credit accounts affected? Thx

  • chezy_geo Cheryl Burnett (@chezy_geo) reported

    @O2 sim swapped over 24 hrs ago and still still have zero network recognition,it briefly allowed text but now its saying no network. No messages from yourself saying there is an issue. After upgrading can you help as I am a carer and rely on my phone.

  • LadyLunaWolf Luna Wolf (@LadyLunaWolf) reported

    After hours on the chat with @O2 and months of trying to cancel the account I am left no further ahead and feeling very traumatised by the whole experience. #badcustomerservice

  • griffsr Scott GriffithsClare (@griffsr) reported

    @O2 very disappointed that had no signal or data at Fairford for the last week. I was told that O2 refused to put extra support in the area due to the air tattoo which is what normally happens. EE provided this for their customers so not sure why you didn’t? Time to change to EE

  • sjacksonAFC Simon Jackson🎗 (@sjacksonAFC) reported

    To everyday contacts, unfortunately my phone was stolen in one ****** part of London today. I am currently only contactable by email. Thanks @O2 for your swift help. To the immigrant who nicked it - I hope you do something positive with the few quid fencing it gives you. ***.

  • ilkleycaraudio Ilkley Car Audio Ltd (@ilkleycaraudio) reported

    @O2 Thankyou for wrecking my credit report with your inaccurate loading of my credit file. You’ve literally pulled my final straw, you’ve lost me as a customer. 2 iPad Pro contracts 2 apple watches 2 iPhone pro max accounts Your loss

  • chellehewison Michelle Hewison (@chellehewison) reported from Whitley Bay, England

    @O2 Any issues in the Whitley Bay (NE26) area with mobile signal this weekend? I’ve barely been able to get 3G at times let alone anything else!
