  • 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.

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • 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!

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • 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.

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • 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

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

    @O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

  • 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

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • 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!

  • 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,

  • Katie65713110 Katie (@Katie65713110) reported

  • Bear230202 colin (@Bear230202) reported

    @LucyEvangeli @O2 Yeah I’ve been waiting since the 3rd of October just called again today for the 5th time to be told they have a back log what a terrible excuse eh

  • arw84 Adam Whiteley (@arw84) reported from Wakefield, England

    @imran18791 @Nathan4376 @O2 Should order through third party. Cheaper, more reliable on the same network and only 24m contracts.

  • hkm279 maira🖤 (@hkm279) reported

    @O2 has the worst customer service ever

  • Hinizzl3 SH (@Hinizzl3) reported

    @O2 can you help me change to an e sim?

  • imran18791 ImyKhan (@imran18791) reported

    @arw84 @Nathan4376 @O2 Exactly what I should have done. But if I cancel now, I'll be waiting even longer

  • DoctorSquee The Doctor Squee Show (@DoctorSquee) reported

    @JaimeGoddard @O2 So his thing is he does less shows because then its only "the real fans" but in truth it means many don't get to see him. It's up to him of course, just seems a shame to not give all fans opertunity to see your stuff they support you in.

  • WrightLights1 WrightFrights! (@WrightLights1) reported

    @pidricpotter Do you just rock up to them and ask for a deal then? My @O2 deal is terrible compared to what EE offer. I pay more than anyone I know and don’t even get unlimited data. Plus reception is terrible when I tour.

  • Britney12Jones Britney Jones (@Britney12Jones) reported

    @O2 has the worst network coverage in the southeast! They just rely on you using Wi-Fi. What’s the point of paying for a contract where you don’t even get 4G! #o2 #networkcoverage
