  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • ollieeden Ollie Eden (@ollieeden) reported from Farnham, England

    @O2 I’ve been a customer for nearly 20 years, but I will be more than prepared to switch if you fund / pay for advertising on #GBNews #DontFundGBNews

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

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

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

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • PGcomms Peter Gordon (@PGcomms) reported from Guildford, England

    @O2 hi there - my 3G/4G data facility on the phone hasn’t worked for some hours. Mobile phone signal ok. Is there a data prob?

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • gonnella Pete (@gonnella) reported from Woodley, England

    @O2 frustrating deal with you guys, 6 months of poor service. Now dealing with your networks team, you quite obviously have a coverage issue in my area. Please just let me leave my sim only contract early thanks.

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

Latest outage, problems and issue reports in social media:

  • primaryteachew Emily Weston (@primaryteachew) reported

    Just upgraded on @O2 who I’m usually so impressed with, but there’s now a signal mast down in my area for the foreseeable which means I can’t be phoned and messages aren’t coming through so I’m missing important calls. Not even contact from them to give any explanation 😤

  • GuyGuycutler5 Guy cutler (@GuyGuycutler5) reported

    @o2 absolute joke of a company cant even tell what moneys they have received even when you provide them with receipt number and customer care that talk english sounds more the 3 back to @VodafoneGroup i go

  • heyhihelloitisI I (@heyhihelloitisI) reported

    Hi @O2 I bought a new sim with yourselves and I gave you my PAC code from Vodafone. I've just put my new sim in and have a different number. How do I fix this?

  • SusanEM68 SEF114 #NoJabs #NoGreatReset (@SusanEM68) reported

    @O2 why is the app not working? Can’t look at my account.

  • BreakingJones Tom Jones (@BreakingJones) reported

    @O2 got stuck in an endless login loop while trying to get @spiritboxband tickets all day and now they’re all gone. Guess have I have to try my luck on Friday for general sale for the London date.

  • Cash1863 Ashley Thorley (@Cash1863) reported

    @O2 hi There has been zero service since Friday seemingly across Stoke. I've tried in ST1 and ST3 postcodes. Your coverage checker says a mast is not working. Service is defaulted to emergency calls only. Will you be refunding all line rental costs until this is fixed?

  • primaryteachew Emily Weston (@primaryteachew) reported

    @Miss_S_Primary6 @O2 That’s what I’ll be asking for - to exit the contract with no repercussion. Rumour is they’ve taken the mast down to convince our council to give them the new mast spot they want…so unlikely to be resolved anytime soon! Hope yours is sorted soon too!

  • Miss_S_Primary6 Laura Spain (@Miss_S_Primary6) reported

    @primaryteachew @O2 Im not even convinced they’re trying to fix our issue, which gets worse depending on where you are in our part of town. We get the occasional message that someone is working on it, followed by one saying the issue has been resolved then back to square one of flagging it.

  • SYMNJAYMS 𝐒𝐘𝐌𝐍 𝐉𝐀𝐘𝐌𝐒 (@SYMNJAYMS) reported

    @O2 I can’t make any calls bc you have deactivated my calling. I’ve been trying to message on the app all day but you’re “extremely busy” so can’t help. I can’t call you. I’m stuck. I’m within my 14 days cooling off so will have to cancel if you don’t help me.

  • Kenstaaa Kenny 🎅 (@Kenstaaa) reported

    @Zenith_UK @O2 @EE EE is terrible. Great coverage, probably the best coverage however, they charge so much more monthly than most other providers!
