  • 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 .

    @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

  • 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.

  • 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

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

    @westspice @O2 Awful service for me today!

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • 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

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

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

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

  • 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. #

  • 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

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • 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

  • 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.

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

  • 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

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • 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!

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

  • Graffi Martin McGrath (@Graffi) reported

    @O2 @e_emobile you guys are always banging on about you “great UK coverage” yet I go from Nottingham to London on the train and the coverage is terrible? I’d get a better reception trekking through the Amazon!! @UKgovcomms you keep telling us to use public transport?? Joke.
