  • 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.

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Yes I usually switch between when my 4G struggles. My calls have been dropping and not working properly too though in a variety of locations.

  • MisCatD Cat 🖤 (@MisCatD) reported from Cardiff, Wales

    @ThreeUK customer service is horrendous

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Have been with @ThreeUK for years and always been very happy with service. However since renewing to a 24 month contract and 5G getting turned on, my service has been absolutely terrible. Terrible or no 3G/4G, calls cutting out or failing. 1/2

  • Dariogutier Darío Gutier (@Dariogutier) reported from Cardiff, Wales

    @ThreeUKSupport Yeah and the problem was still there, my phone was changed because apparently was the phone and the problem is still here! It’s been 2 years contract in hell!! I can’t wait to finish it

  • 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.

  • 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

  • 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

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DJAshBash @ThreeUKSupport I'm a Three user and have had experience of both good and bad network in and around the Cardiff area. What Three are stating is true but it's taking longer than they planned originally. Three have the largest 5G bandwidth allocation of all the UK networks plus they also have..

  • alunT Alun Thomas (@alunT) reported from Caerphilly, Wales

    @ThreeUK network down after I ios update overnight #threedown

  • 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.....

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

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

  • 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

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    On hold to @ThreeUK possibly the worst phone company i’ve ever encountered in my whole life

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DanielIqbal1999 @ThreeUK That should not happen. If the Three signal fails a 999 call should automatically be routed through any alternative network .

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    @ThreeUKSupport Worst company i’ve ever encountered. No wonder why your basically failing as a company

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    @ThreeUKSupport Worst company i’vr ever encountered

  • thefraudguy_uk PeterT - TheFraudGuy & Godfather of Anarchy (@thefraudguy_uk) reported

    @UK_Daniel_Card @ThreeUK It has been great to see how the community have reacted to this and how these folks have shot themselves in the foot reputation wise. Too much of this is spite because a sales pitch failed IMO. The pitch failed because the vendor was talking broken biscuits.

  • miles527 Miles (@miles527) reported

    @ThreeUKSupport I haven’t been given any information on Twitter yet about this issue that’s the problem. I have also contacted Three CEO, COO and Executive Office 🤔🤨 The speeds in the evening are utterly appalling.

  • harrisonb360 harrison (@harrisonb360) reported

    @ThreeUKSupport 0333 300 0330 0333 300 3333 both these are not working and well i went in store today about my beats headphones that i got with my contract cause they didn’t work many more and they said to go apple and get them fix and you guys will Reimbursed me or something

  • levivibe Peejày (@levivibe) reported

    @ThreeUKSupport is there a problem with the three network? Can't make or receive calls.

  • miles527 Miles (@miles527) reported

    @ThreeUKSupport My question is a general one - is the mast in Portishead being upgraded to The Big Network Build project? I’ve been told this is the reason however there is nothing on the network status page.

  • knav2013 knav2013 (@knav2013) reported

    @ThreeUKSupport balance of account suddenly dropped. I asked support to send me the numbers called, duration and date/time of calls. Support said relevant team will send me these within 48 hours. Not heard from any team since then.

  • ant_kenyon Incubus (@ant_kenyon) reported

    @ChipperCZ @ThreeUK Mine too! Last straw this...****** network for past year and now no phone signal! @EE Sign me up

  • StarlightMcKenz StarlightMcKenzie 💙 (@StarlightMcKenz) reported

    @ThreeUKSupport They say they have sorted it, - but they always say that. They refuse to give me any evidence that the issue ever happened or that they have any commitment to resolving it. They give me reference numbers to info THEY hold but won't tell me what that info refers to.

  • LesleyLesleybd1 Lesley boyd (@LesleyLesleybd1) reported

    @ThreeUK is there a problem at the minute with network?

  • SwootiestSweet Ben Gerrard (@SwootiestSweet) reported

    @ThreeUK I appreciate that you are making the network better, which is great, but can you not do it in the middle of a ******* weekday. It's taking the ******* piss.
