  • joe_bignell Joe Bignell (@joe_bignell) reported from London, England

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @JayTaylor_93 @O2 I literally get two bars everywhere. It’s so bad. Really disappointed

  • mesner5 Mark Esner (@mesner5) reported from Borehamwood, England

    @O2 been with you 10+years you have my money each month never had anything in return

  • stourdave Dave (@stourdave) reported from Tottenham, England

    @O2 Yes #stop please **** off with this shit. I only accidentally liked your ad while I was scrolling and you've bombarded me ever since. Your signal is shit anyway.

  • 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

  • paullferrer Paul Ferrer (@paullferrer) reported from Harrow Weald, England

    @O2 Two weeks later still have low signal and no one is telling me when it will be fixed you pass me to Sky Mobile who say its your masts they use and contact you

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • 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!

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • Henry_Coates Henry Coates (@Henry_Coates) reported from Walthamstow, England

    @jimsmallman @O2 I left them a few years ago because the customer service is god awful! @ThreeUK is the best bet for the amount we travel! Not the best in London but all over the world it’s great

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @thebrownvixen @O2 It’s the worst

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @KateAlexa_ @O2 IT IS AWFUL

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • Kineets Kineta Kelsall (@Kineets) reported from Tottenham, England

    @Armaanilyas2 @O2 It’s so crap!

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • 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.

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • HaleAlexander Alex Hale (@HaleAlexander) reported from London, England

    @O2 @RugbyXOfficial What a shit show the organisation is at the O2 tonight.. #nopoint

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

    @O2 How did this shit happen

Latest outage, problems and issue reports in social media:

  • dopey000 Dominic Doyle (@dopey000) reported

    @O2 I’ve done this all several times. Makes no difference. A brand new 5g sim and a iPhone 13 Pro Max. Wife has exact same issues amongst other friends locally. It’s obviously a problem at your end.

  • TomElliotW Tom (@TomElliotW) reported

    @EnglandRugby @autumnnations @O2 Great to see Murley in the squad, he has been unreal. Ollie Lawrence and Joe Marchant have been absolutely robbed by not being included. Never thought I'd say this, but drop Sam Simmonds. He won't be available for the world cup next year so give someone else a shot.

  • TomHowellhuman Thomas Howell (@TomHowellhuman) reported

    @EnglandRugby @autumnnations @O2 No Alex Mitchell Idiot

  • Earl_67 Earl Dawkins (@Earl_67) reported

    @O2 I have never had a problem with 02 until today and I am fuming. They’re making their problem my problem and it will impact my credit rating negatively. I’ve changed my billing date and I have since been billed pro rata only to start being harassed since this morning

  • EC_316 Elise Clarke (@EC_316) reported

    @o2 very disappointing customer service - spoken with 3 different advisors - who claim to resolve the problem but clearly are not listening or just ignoring a simple request -

  • ealingowl John Drabble (@ealingowl) reported

    @O2 tried sending you a direct message about the issues I’m having. You’ve ignored it. Can’t get anyone in your customer service department to sort it. Useless.

  • BradshawCymru Martin Bradshaw (@BradshawCymru) reported

    Not had any internet at home for 4 days, so I’m trying to rely on my @O2 network. But I’ve realised how bad the network is in my area. It’s time to say goodbye 👋🏼

  • chezza83 cheryl naylor (@chezza83) reported

    @O2 I have been dealing with a in correct bill since the 16th August and still not sorted and today I get told they will not take the £6 late payment off yet the fault is with yourselves not me!! Disgusting service can't wait to leave O2 and i have been with you for over 20years

  • andyrennie Andy Rennie (@andyrennie) reported

    .@O2 Once again Tq1 has no service with O2, only works when they want it too……..time to do the same with paying my bill, cancel the DD and pay when I get mobile coverage

  • abzpaul Paul 🚁 (@abzpaul) reported from Bucksburn, Scotland

    Hello @o2 I sent a few DMs over the weekend as I'm having problems inputting my PAC to enable me to move my number from @VodafoneUK to yourselves. The PAC expires 19th Oct. I'd like to move it 18th Oct but your system won't accept my info
