  • 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.

  • 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.

  • 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

  • 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

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

    @O2 How did this shit happen

  • 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.

  • 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!

  • 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

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

    @thebrownvixen @O2 It’s the worst

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

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

  • 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

  • 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

  • Ian_G_Phillips Ian Phillips (@Ian_G_Phillips) reported

    @O2 Issue identified in this area. Hoping your engineers can weave their magic and fix ASAP

  • ApolloBelladona ☆ Apollo ★ (@ApolloBelladona) reported

    @giffgaff Tbh GG are not really in a position to solve it, @O2 are, since you ride off them. More than 2 yrs ago I reported That there was absolutely no GG data to be got in Peckham or Nunhead in S. London, even with a full phone signal. Haven't been able to open a Web page for years.

  • SeanRuddockk Sean Ruddock (@SeanRuddockk) reported

    Every few months i'm having issues with @O2 mobile data. I'm in the cardiff area and I cant use mobile data at all, yet I have 13gb of data left. Its not been working for 48 hours. Please solve it or ill be looking else where

  • PaulHag87 Paul Haggerty (@PaulHag87) reported

    I hope @O2 treat their paying customers better than the service I just received and I'm not even with O2! Had the misfortune of calling customer services at lunchtime and it was horrific. Rude, unhelpful and a waste of time. #O2 #mannerscostnothing

  • draceya1 draceya (@draceya1) reported

    @O2 Hello, I’m sorry but the o2 customer service online is the absolute worst. Could you please help me? It’s urgent, thank you!

  • chris_greenf Chris Greenfield (@chris_greenf) reported from Wymondham, England

    @EE Nah, Orange was better than T Mobile, but when you merged, the quality and signal went to ****. @O2 is miles better, and so far haven’t hit anyone with roaming charges either!

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • DorbanNic Nicola Dorban (@DorbanNic) reported

    @Stewart28842550 @O2 Ah, so you’re having problems with a contract agreed with them which suddenly costs twice as much and bears no resemblance to the agreement.

  • maisonblanc_ Alli ✨🪦💀🎃 (@maisonblanc_) reported

    Anyone else had full-on issues with @O2 coverage today? Or do the fates just want me to get a new phone? #Shiny

  • DarrenMcMenami1 Dazzer (@DarrenMcMenami1) reported

    @O2 why is the signal in Strabane BT82 9FJ so poor
