  • n1spm Sean Meade (@n1spm) reported from High Wycombe, England

    Following a recent mobile roaming incident (connected to a Bosnian network 4.5km+ from Dubrovnik airport), it did make me wonder why phones don’t have tiered roaming settings e.g. within EY, outside EU etc @Apple @o2 #roaming

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • 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.

  • 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

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

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • LyndallAnn Lyndall (@LyndallAnn) reported from Hounslow, England

    @O2 This issue started a few weeks ago for me and my friend has had the same issue so changed phone companies a couple months ago.

  • Stefan_baisden Delboybaisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    5th day in a row I've had no signal or data through to my phone. @O2 is going downhill. Definately on its way out. This is so poor I shouldav stayed with T Mobile. #O2 #POORCUSTOMERSERVICE

  • BecOz14 Bec Osborne (@BecOz14) reported from Camberley, England

    Have had 1 bar of @O2 signal for most of this year, funnily enough when I tested the signal strength back in July the signal jumped to a MEGA 2 bars momentarily. #NoServiceHere

  • PandaEyesKirsty Kirsty Ann (@PandaEyesKirsty) reported from Maidenhead, England

    @AmazonUK I have made a large order and it has been delivered to a Amazon locker. This locker is in a private @O2 building. THIS WAS NOT STATED AT THE TIME I ORDERED! Now they're refusing me access so my daughters birthday presents are not able to be collected!!😭 HELP!

  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • Stefan_baisden Delboybaisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 has GENUINELY the worst Phone line #Customerservice system ever. I've never been more infuriated just waiting to give a password or speak to someone. Please #O2 update your system to 2019 standard asap.

  • 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

  • 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!

  • jayblake_ Jay Blake (@jayblake_) reported from Marlow Bottom, England

    Dearest #02 @O2 I do wish all your customer service people were as helpful as the person I spoke to today. Sadly there were several trees killed in the printing of a years mobile bills, which I was told was required. Todays agent simply gave the info I needed in a 5 min call

  • Nick_G6 N I C K 🇿🇼 (@Nick_G6) reported from Hounslow, England

    Dear @o2 and @StarlingBank it’s been two weeks and I still can’t believe that I cannot pay my phone bill via the app! Please send help I’m all out of options here. Now I’m accumulating charges for late payment 🤬🤬🤬

  • miajohnston1967 Mia Johnston (@miajohnston1967) reported from Bracknell, England

    @O2 very poor customer services fuming is an understatement 😡

  • 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.

Latest outage, problems and issue reports in social media:

  • FACTteam TitsUpproduction💪💙 (@FACTteam) reported

    Having awful problems with @O2

  • The1andOnlyPK Paul (@The1andOnlyPK) reported

    @BorisJohnson @virginmedia @O2 Much more expensive Sims to pay for this "free" service. If you don't travel or won't travel a lot. You will save a lot of money by using another provider

  • itskyleflamson Kyle F (@itskyleflamson) reported

    I’m rather concerned about @TelefonicaUK / @O2 trying to oppose #PrivateRelay for #iPhone. Almost like they dislike the idea of customer privacy, which sounds suspiciously like @Facebook disliking user privacy so they can sell our data to advertisers.

  • vallendemain Val Lendemain #FBPE #FBPPR (@vallendemain) reported

    @NadineDorries @virginmedia @O2 Just how ******* stupid do you think we are, Nadine Dorries?

  • apluspj Ali PJ (@apluspj) reported

    @O2 I went to Caffè Nero to use my coffee voucher, downloading voucher just before I got to the door as reception issues inside the shop but they had locked the door as they were closing an hour earlier than advertised. Is it possible to cancel my voucher so I can use it 2moro?

  • BlokeOfWords Mark Williams (@BlokeOfWords) reported

    @NadineDorries @virginmedia @O2 That is simply a lie. In any case, you could issue the same mandate, but you don't because it might stifle Party donations.

  • TomSmit64578800 Tom Smith (not that one) (@TomSmit64578800) reported

    @O2 Things like this are what keeps me as an O2 customer

  • FifeArab Ali Watt 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇸🇪🇺💙 (@FifeArab) reported

    @NadineDorries @virginmedia @O2 If you and your corrupt mob of fellow idiots hadn’t dragged us out of the EU, mobile roaming wouldn’t be an issue.

  • UK_Centrist John 💙 🇬🇧 (@UK_Centrist) reported

    @BorisJohnson @virginmedia @O2 Good PR for them, but no assurance for consumers it won't change in future. A far worse deal than the one we had where it was mandated. But we have a truly corrupt and awful government.

  • Judithrhion Judith 💙#FBPE#SackReesMogg (@Judithrhion) reported

    @NadineDorries @virginmedia @O2 But rather than address this narrow problem, the UK government took a deregulatory approach and removed any limits on retail roaming charges.
