  • thisisjmx James Vincent 🏳️‍🌈🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Cardiff, Wales

    @ThreeUKSupport Yeah there weren't any issues. Just no inside signal. There was definitely no 3G & no VoLTE either. Just thought I'd mention it. Mayb a consideration for future network upgrades.

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport Been through this, you won’t check as it’s a business account and the business team never follow up. 2 years ago Caerphilly had around 40mb down now it’s about 4mb down and no one there seems bothered.

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RIKZ200 @EE @jay_smithy_13 @ThreeUK I couldn't agree more. 3's coverage is the worst of them all. Duped by their lying 'coverage' map. Can't even get a signal in my house. Roll on moving back to #EE

  • TheMMEvent Mike Anthony Moreno (@TheMMEvent) reported from Cardiff, Wales

    Another day where @ThreeUK fails to provide decent phone service. I’ve got full signal but yet my services is so slow. #whatamipayingfor

  • Mrs_Thomas82 Sarah Thomas 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Mrs_Thomas82) reported from Maesycwmmer, Wales

    @ThreeUK My service has been fine. My husbands on the other hand has been non-existent since last night.

  • thisisjmx James Vincent 🏳️‍🌈🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Coity, Wales

    @NoServiceHereUK CF311RQ, Prince of Wales hospital. Very poor inside signal from @ThreeUKSupport and @VodafoneUK. Just thought I'd point it out. #NoServiceHereUK.

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • Kickassempress Anastassia Cassar (@Kickassempress) reported from Treorchy, Wales

    @ThreeUKSupport hi I have no signal at the moment and I was wondering if there was any maintenance going on here. Cf42 6lb

  • mindspits Rhys (@mindspits) reported from Cardiff, Wales

    @mythofechelon @TMobile Could be a @ThreeUK issue as their network was down overnight.

  • Moe3k9 C-Note (@Moe3k9) reported from Cardiff, Wales

  • TicketTattle Andrew Thomas (@TicketTattle) reported from Cardiff, Wales

  • richieh Richie H  (@richieh) reported from Caerphilly, Wales

    @ThreeUK @ThreeUKSupport Haven't had any service at all since yesterday and still nothing, with a business to run.....

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport No improvement after a restart and I tried 3 different phones so I know it’s not my phone. The phone is on 3G most of the time anyway and it is around the same speed as 4G. The signal is absolutely terrible.

  • WildthingJ74 Johnathan Williams (@WildthingJ74) reported from Cardiff, Wales

    @samboc86 @hockey_laura @Apple @ThreeUK I hate change and I'm sure they bank on being being apprehensive about it. I'm never going back to them

  • AnnaB_Cdf Anna Brzezinska (@AnnaB_Cdf) reported from Cardiff, Wales

    Just came back from North Wales and thanks god I have a sat nav & sos button in my @MercedesBenz as otherwise my journey in the morning would involve searching for an actual road map since @ThreeUK was down, so no service nor data during 4h journey from Cardiff 👎😑🙄 #threedown

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @JohnDubyaUK @ThreeUK Yeah they’re all in such a rush to get 5G out, they just seem to have given up on trying to get 4G sorted out. At least show me I’ve got a crap signal, don’t pretend it’s all full speed and awesome.

  • stumpy_juk Matthew Jones (@stumpy_juk) reported from Cardiff, Wales

    @ThreeUKSupport network issues in Cardiff..

  • oxWelshElisexox 🏴󠁧󠁢󠁷󠁬󠁳󠁿Welsh Elise🏴󠁧󠁢󠁷󠁬󠁳󠁿2k (@oxWelshElisexox) reported from Cardiff, Wales

    @EnglishPhoebeX1 @ThreeUK @ThreeUKSupport **** mines been cutting out on calls but not no network

  • thisisjmx James Vincent 🏳️‍🌈🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Cardiff, Wales

    So 2 weeks ago there was a 4G issue in my village with speeds in kbps range. It's been better but last few days now fine 50-70 Down, around 18 Up. @ThreeUKSupport It's not easy when living a completely mobile network operator life. No home fixed ISP. 1/2

  • wickedwitchgal Sarah Beth James/Lucinda Greyhaven (@wickedwitchgal) reported

    @ThreeUKSupport Then terminate the account. Like I have asked a hundred times now! In every legal way. With a million security checks. I have asked nicely. Less nicely. And Im now annoyed enough to make it a public issue until this is resolved or see you in court!

  • chrisjbrogan Chris Brogan (@chrisjbrogan) reported

    @ThreeUKSupport Still same issue

  • wickedwitchgal Sarah Beth James/Lucinda Greyhaven (@wickedwitchgal) reported

    @ThreeUK @ThreeUKSupport day one of tweeting your accounts until you terminate my contract. Trust me. I won’t stop until you do. So avoid the bad press. And do it. All my details in your inbox.

  • wickedwitchgal Sarah Beth James/Lucinda Greyhaven (@wickedwitchgal) reported

    @ThreeUKSupport I’ve been arguing with your company since June. First over a land internet that never worked. Then over bad mobile net. And Im just done now. Been with your company years to be treated like this. Not happy. Just want to leave. Got a new contract with @VodafoneUK

  • harrietjonesmus Harriet Jones (@harrietjonesmus) reported

    @ThreeUKSupport Still not working guys :(

  • wickedwitchgal Sarah Beth James/Lucinda Greyhaven (@wickedwitchgal) reported

    @ThreeUKSupport Inboxed the details. Terminate the account or sue me. I will screen shot and show all the proof I attempted termination. Im done fighting with fools.

  • EnvoyCDX Gary McKie (@EnvoyCDX) reported

    @ThreeUKSupport so, what is with the cancelation roundabouts? I simply want to cancel the contract (which I asked for 30 days ago!) now I am being told a code has expired and I have to provide another 30 days notice? Screw that! Sort it out Three..

  • harrietjonesmus Harriet Jones (@harrietjonesmus) reported

    @ThreeUK Hi guys, I can't top-up my phone. because I can't sign in (because I can't top up) please help :/

  • wooffet wooffet (@wooffet) reported

    @ThreeUKSupport @ThreeUK Are there any issues in the CM3 area that you are aware of? Have ok signal but 4g data is essentially dial-up speed, and get absolutely no 3g signal. 0.5Mbps down, literally 0Mbps up, it's totally unusable. The network status checker shows nothing...

  • hypernova00101 lol because my tweets violated twitt.er 'rules' (@hypernova00101) reported

    Hey @ThreeUK there should be an option to transfer any cash/ reward to three account (that way customer can just use it to offset line rental costs)
