  • 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

  • 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.

  • 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,

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

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

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

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

  • 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

  • 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. #

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

    @westspice @O2 Awful service for me today!

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

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

  • 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

  • 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

  • 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

  • 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

  • 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!

  • 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

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

    @Dyrojo @O2 Same it’s awful!

  • xldnxx xxld (@xldnxx) reported

    The award for the worst public wifi has got to go to @CloudwifiInc absolutely awful. Wanting to run into a cafe to quickly use wifi snd the process takes around 20 minutes? Horrific. Will make a solid effort to never use again. Thanks @O2 for your seamless, one click process

  • Aaron_F320 Aaron (@Aaron_F320) reported

    O2 signal at Gatwick Airport is the absolute worse. I never get 4G and reception to try and make calls is really patchy. Time to change network I think @O2

  • thepeterhunt Peter Hunt • CDG • CSA • (@thepeterhunt) reported

    @O2 possibly the worst network ever! And try to get any help from customer services… good luck! 😡

  • bonbons84 B Miles (@bonbons84) reported

    @O2 Hi, I am having trouble getting a PAC code, ive tried all routes to get this, online, phone, online chat and here. Can you please rectify this, it feels like you're giving me no option to leave.

  • MatthewDixon32 Matthew Dixon (@MatthewDixon32) reported

    @EnglandRugby @O2 Just….we have world class back row players and Itoje is a world class second row. So of course we go worst of both worlds and play a ridiculous line-up with zero inventiveness. At least Argentina will probably be entertaining.

  • infobleep Tim (@infobleep) reported

    @O2 hi. When in Greg's, Guildford this morning, I was told codes are not working. Unfortunately I had already selected use the offer. I don't know if this is a national problem but one voucher has just been wasted, which someone else could have used later if I'd known. Cheers

  • Hanrealistic Han Realistic (@Hanrealistic) reported

    @O2 Your website is soooo stupid, I can't even find Sign out option. So I can login with different account. Want to contact, but NOOOOOO it's a sin.. I can't contact with you. So bad service.;

  • capnmac85 capnmac 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦 (@capnmac85) reported

    @O2 There is no damage to the device. This is a replacement device given to me in February which has had intermittent network connectivity issues. All previous issues were resolved by turning on and off again or removing sim card. This time however nothing is fixing this

  • craigyoung79 craig young (@craigyoung79) reported

    @O2 having issues with no data on 4G & 5G in built up areas. Major issue. Yet every time I try to use the “chat” system on your app it says “sorry we are very busy please try again later “ and ends the convo. I wonder why your so busy 🧐
