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

  • 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!

  • 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,

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

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

  • 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

  • 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.

  • 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.

  • 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

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

    @westspice @O2 Awful service for me today!

  • 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!

  • 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

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

    @O2 How did this shit happen

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

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

  • 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

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

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

  • 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!

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

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

  • 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

  • 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

  • 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. #

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • Guptathegreat Chris Hall (@Guptathegreat) reported

    @O2 Over 10 days now with no mast signal (CM3). Messages like ‘We working hard to sort it…’ ‘Please be patient…’ hardly works, when I can’t phone (receive calls) message (receive messages) or use data when I leave the house. Update by 29th Oct - am I to wait a further month?

  • inbetweeters Grumpy Buggers (@inbetweeters) reported

    @Chrissyd27 @O2 Stock issues happen. I think a change @O2 could look at implementing is a live stock status when it comes to online sales though, in the same way most retailers do.

  • Chrissyd27 ChrissyD (@Chrissyd27) reported

    @inbetweeters @O2 We all in same boat it seems.. but completely lied to me, happy to let me start a new contract, but not happy to deliver phone when they said, I was told 2 weeks, its over 2 weeks now and customer services was useless, they said they didn't know, and u get no email updates at all

  • lauramckeown__ laura (@lauramckeown__) reported

    @molly82267742 @O2 Oh wtf, they won’t even reply to me other than to say that the wait time on the website won’t be the same as my wait time!🥴 I’d rather cancel it now and just go somewhere else

  • kellyparish81 Kelly Parish (@kellyparish81) reported

    @O2 @TheO2 WASTE of TIME & STOLE money from me all bcoz I sent 2 text messages which cost me over £4 they were V.RUDE, UNHELPFUL & down right DISGRACEFUL!! Had an operation Saturday& NEED this credit! NOT much 2 a multimillion £ company! Wot network do I go with now? LOYAL,NOmore

  • HennaK__ H. (@HennaK__) reported

    @O2 by far one of the worst networks I’ve ever come across!

  • sebiwill83 S.. (@sebiwill83) reported

    @omotayo_one @O2 Congratulations 🎊 I never get surprised by @O2 only disappointed with poor services in my area 😢

  • devon000001 tyeler4 (@devon000001) reported

    @O2 what is wrong with your 4g ? I’m struggling to get a signal anywhere. Not exactly what I pay for

  • Chrissyd27 ChrissyD (@Chrissyd27) reported

    @DigitalPrime @O2 @SamsungMobile Alsolute disgrace they sell u a contract on the basis of a lie! I was told 2 weeks for mine, over 2 weeks and customer services didn't have a clue, AND they don't keep you updated by text or email at all

  • ichopanimals Joe 🅴 (@ichopanimals) reported
