  • 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!

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @westspice @O2 Awful service for me 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.

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 remember few months back when @o2 was down for nearly 2 days.. after that it’s service is going down everyday.. sometime when you are travelling and passing from certain areas O2 service will simply shift to 3G form 4g and sometime it will be No Serive at all 1/2

  • 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

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    every single day your service going down ,moved to O2 from 3 , paying more getting less as compare to 3 but your service is kind of same , most of the places it just disappears, call failed, hardly one bar most of the time and no service at certain places.. v disappointing @O2

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 i have few screen shots of different areas when it’s service just disappears, call failed and only 1 bar, will share screen shots with @O2 3/3

  • 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

  • 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 .

  • 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.

  • 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!

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • OmarMansoor Omar Mansoor (@OmarMansoor) reported from London Colney, England

    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

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

  • cliveaustin2 Clive Austin (@cliveaustin2) reported

    Absolutely disgraceful customer service from @O2. 5 days been trying to sort a problem, 5 hours + overall on the phone and still not resolved. Phone been put down on me, lied to, on hold for hours, transfered here and there. They won't be getting my customer when this is sorted.

  • chirango Angela Cordell (@chirango) reported

    @O2 I am trying to contact customer service for 3 days now. Can I please have an email or a telephone number so I can speak to someone!!! @poorcustomerservice

  • misshuncho_ 𝔉𝔞𝔦𝔱𝔥 (@misshuncho_) reported

    @O2 Yes everywhere. Told me to reset my phone with airplane mode on then off etc and that it will be back to normal after a few minutes ... it’s been over a week. Fix it please.

  • ScottWhitto Whitto (@ScottWhitto) reported

    @day82_ @O2 I've never had that, this is first problem I've had and had pixels since the start

  • antongottlob antongottlob (@antongottlob) reported

    @O2 my entire network is down in E8, London. No calls or text working although showing signal and no data. Are you working on a fix ? thank you in advance.

  • craftybeesixty3 🧲rafty bee 6️⃣3️⃣ (@craftybeesixty3) reported

    No help at all from @O2 been without service for 8 days and no help at all! They suggested I use WiFi calling when the network themselves have blocked it on my device! Absolute joke!

  • JourneyClaires ClairesJourney (@JourneyClaires) reported

    @O2 is there an issue with signal today? I've not had any signal this afternoon.

  • P_Leyshon Paul Leyshon Ⓜ️🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@P_Leyshon) reported

    @O2 It’s the phone signal... or lack of it. Always had a full signal at home, but since the weekend a “ no service” is displayed. Away from home, all ok.

  • Emma75155788 Emma (@Emma75155788) reported

    @O2 your telephone service and customer service is absolutely disgusting! I have had an ongoing issue since May 2020 I call i every month get told a mange will call me back and no one ever does!! Each adviser tells you something completely different..incompetent! Causing stress!!

  • sophieroutledge Sophie (@sophieroutledge) reported

    @O2 I’ve just had a random number messaged me asking who I was as I had apparently called them and asked how they were and hung up. They provided a screen shot with my number as incoming then above they tried to call me back. Help as I didn’t call anyone I didn’t have my phone 🥺
