  • 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.

  • 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!

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

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

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

    @Armaanilyas2 @O2 It’s so crap!

  • 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.

  • 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.

  • 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

  • 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!

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

    @thebrownvixen @O2 It’s the worst

  • 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.

  • 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

  • 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!

  • 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.

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

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

  • 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!

  • 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.

  • 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

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • kxdz_m cuff it ✨ (@kxdz_m) reported

    .@O2 I’ve been waiting 72 hours for a manager call back for an issue I’ve complained about 3 times now. Do you guys just get off on ignoring customers?

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @trotttrott3 @O2 The networks congested, it’s not fit for purpose, masts all over the place are termed ‘busy’ which really means congested. Too many devices try to access poor infrastructure. I suggest retweeting complaint using BBCWatchdog, WhichUk, ofcom and Martin Lewis tags

  • kxdz_m cuff it ✨ (@kxdz_m) reported

    @O2 My connectivity with O2 is dire. I’ll have 4G or even 5G and get 2mbps speed or even time out. I’ve done a SIM swap, reset my phone & the issue is still there. I was told by your call centre that manager calls can only happen w/ a scheduled call back. It’s been 72 hours 😐

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @Snaipes1889 @O2 If uour not happy then retweet complaint and add BBCWatchdog, WhichUk and ofcom tags, only way they going to listen and maybe fix the awful network

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @r_you_rosa @O2 If they still haven’t meet your needs, retweet your complaint with BBCWatchdog, WhichUk, ofcom and Martin Lewis tags. The network is horrendously bad.

  • BIGalan247 Alan Dyer (@BIGalan247) reported

    @O2 your coverage is shocking! I have been in Scratby a few miles from Great Yarmouth and all the while I was there had no signal at all! Everyone else in my party who is with EE had 4G/5G. Something needs addressing there!

  • magsfoxyloxy Maggie (@magsfoxyloxy) reported

    @O2 still paying for international roaming and still not even getting 3G, let alone 4g. Never ever travelled to Orlando before and had such bad connectivity. Tried selecting network, won’t let me. Tried turning phone off and on and still doesn’t connect. So frustrating

  • DanGreen1986 Daniel Green (@DanGreen1986) reported

    @O2 @jayef99 Also having the same issue

  • eagleeyedferret Adrian Simcox (@eagleeyedferret) reported from Urmston, England

    @O2 3/3 only conclusion I could reach is that your call centre staff are under pressure to make more calls and now routinely disconnect customer calls after a period of making no progress. What do you think??

  • GJJ1A GJ (@GJJ1A) reported

    @O2 Have still no managed to transfer my number after 6 days. No sensible responses from support team. Shambolic. #CustomerService
