  • 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!

  • 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!

  • 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.

  • 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.

  • 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.

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

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

  • 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.

  • 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.

  • 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 .

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

    @O2 How did this shit happen

  • 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

  • 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.

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

    @westspice @O2 Awful service for me today!

  • 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!

  • 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!

  • 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

  • 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!

  • craiginscotland Craig Arthur 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@craiginscotland) reported

    @O2 Have tried airplane mode and rebooting iPhone but still no service.

  • FullSen70316301 FullSend (@FullSen70316301) reported

    @KerrieMalone19 @O2 Well I have started a complaint with @financialombuds and they will be investigating now because I swear man the way they just hang up on you and how rude they are on the phone the day I took the contract out he lied to to sell me the contract

  • rassami Rassami Hok Ljungberg (@rassami) reported

    Exasperation w @O2 reaching new heights as none of their systems nor departments connect and hence the #customerexperience is pure Kafka #FAIL If it were not for the wonderful professional O2 Guru team with Akash and Eben I would have given up, taking my biz elsewhere

  • RO55CO1 Ross Jones (@RO55CO1) reported

    @O2 still **** reception, no where near EE. Wish I never changed 😢

  • ALIF_1988 ᗩ ꪶ 𝕀 ᠻ (@ALIF_1988) reported

    @O2 I called earlier today and spoke to customer service and all they said will send you out a new SIM card! This is rubbish, now I can’t even make calls/txt I got no reception, I don’t live in a farm! I’m in the city of London, what is going on?

  • craiginscotland Craig Arthur 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@craiginscotland) reported

    @O2 Was today, supposed to be complete by 6pm. MyO2 shows the ported in number, if I call it I get the O2 answerphone, but restarting phone shows “no service”. Bloke on phone said I need to go to a shop for a new esim as porting in needs a new sim…

  • craiginscotland Craig Arthur 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@craiginscotland) reported

    @O2 ported in a number to an existing esim today and now have no service, do I really have to go to a shop for a new esim? Feel like I was fobbed off on the phone just now😭

  • tmw1000 Tina Walsh (@tmw1000) reported

    Upgraded phone and tariff with @O2 today, sim from old phone backed up last week, assistant refused to put it in new phone ('googlemail won't be backed up'!!) and said to use 'smart switch'. Guess what - it doesn't work and am now left with two useless phones.

  • parfait_pls unceremoniously thrown out (@parfait_pls) reported

    @O2 Pointless. @o2cando does not care. This issue was brought up months ago, countless times. Nothing has changed. It's just frustrating when I need to get work done :/
