  • 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.

  • 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!

  • 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

  • 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.

  • 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!

  • LydiaElenaxo Λυδια-Έλενα (@LydiaElenaxo) reported from Tottenham, England

    After 11 years with @O2 they are really trying my patience today.. I’ve been a loyal customer and honestly upgrading has been horrendous with you.. I think @EE might be my new home from today

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

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

  • 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.

  • 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!

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • 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!

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

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

  • 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.

  • bks67 bridget sparks (@bks67) reported from Hertfordshire, England

    @O2 I do have the app, I think I will phone the customer service team and ask them,

  • 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!

  • Steve_Edwards77 Steve Edwards (@Steve_Edwards77) reported from Hertfordshire, England

    @westspice @O2 Awful service for me today!

  • 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.

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

    @O2 How did this shit happen

    @JR_CPFC @virginmedia @O2 Are you getting an issue where it just crashes the app down?

  • ellscxo ε (@ellscxo) reported

    @O2 hey, would you be able to help me on here rather than phones as I've been waiting a very long time and my online requests won't work either.. just trying to get my old number onto my new sim!! I have the PAC code but you can't process my request?? Pls help 🙏

  • kyleslnger ks (@kyleslnger) reported

    @O2 I've been having problems paying my phone bill. Everytime I enter my card details it says the payment has failed and need to contact my bank, I did, and they said that a payment was never shown. I tried logging into MyO2 and it shows an error message once I've signed in

  • MattHowland79 Matt Howland (@MattHowland79) reported

    @EnglandRugby @Springboks @O2 Where’s the blistering pace in the backline???? Radwan a differentiator, someone defences are petrified of. A lack of tries is a serious problem for England. We need an inform winger with world beating pace and two out and out centres please Eddie.

  • woowoolover tracie (@woowoolover) reported

    How do I make a complaint to O2 that actually will get resolved. 😭 @O2

  • HardingJay1981 Jay Harding (@HardingJay1981) reported

    @O2 is your customer service always this bad

  • madmac2003 Darren Wright 💙🇺🇦🇬🇧 (@madmac2003) reported

    @kylesoo @O2 Same with @ThreeUK very poor

  • TerryPritchar17 TerryPritchard (@TerryPritchar17) reported

    @O2 Okay but that's not answering my question regarding if you have a problem with the app or not

  • join4te Jay (@join4te) reported

    @O2 Day 10 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • Charlottmansell Charlotte Mansell (@Charlottmansell) reported

    @O2 please urgently reply to my em. You have taken £250 from me without authorisation for a sim that I could never use as it did not work so cancelled straight away! Despicable from you considering these hard times at the minute!!!!!
