3 (Three) Issues Reports Near Cardiff, Wales

Latest outage, problems and issue reports in Cardiff and nearby locations:

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

    @DJAshBash @ThreeUKSupport ..a new chunk of 4G 1500mHz aka Ban.d 32. When they're actually commissioned the Three network has huge potential to deal with all these issues virtually overnight. Sadly they don't communicate the cause and ther solutions very well hence disappointed customers.

  • 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

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

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

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

    @ThreeUK network down after I ios update overnight #threedown

  • 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

  • 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.

  • 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 .

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

    @DJAshBash @ThreeUKSupport @VodafoneUK @ThreeUK I am also on Vodafone. And I would agree they now have overall a formidable network But they have less bandwith 5G than Three..50mHz as opposed to 140mHz so when Three eventually launch 5G 5G it'll be interesting how it all pans out.

  • 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.

  • 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

  • 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

  • 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.....

  • 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

    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

    @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..

  • 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

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

    @ThreeUKSupport Is the same whit whatever I do. Every area I’m going specially when is crowded around me. I have changed SIM cards, phone and the problem is still here

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

    @ThreeUKSupport Worst company i’vr ever encountered

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

    @ThreeUK customer service is horrendous

  • 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

  • AnnieHalli Annie Halliman (@AnnieHalli) reported

    @ThreeUKSupport I've been having issues with connection coming and going during calls for the past few weeks. Is this the network or my phone?

  • JueyDavies Julia Davies (@JueyDavies) reported

    @ThreeUKSupport hi Three, my pensioner age Mum is struggling to access the new app. She has tried live chat but the issue is still unresolved. Apparently access code you send, which is supposed to be active for 10-mins, doesn’t last long enough to login.

  • nathanadkins71 Nathan Adkins (@nathanadkins71) reported

    @ThreeUKSupport Hi can you help with something? I recently changed my number on my SIM but now need the old number to recover an email. Is there any possible way I can access a text from my old number?

  • AndrewChqng AndrewChqng (@AndrewChqng) reported

    @ThreeUKSupport A SM-A715F and a Moto G7 power. It's the postcode for our address. We don't have any issues except the occasional dropout for a few secs but that's more likely problems on our side. It's weird because exactly at 8pm we go from just unstable audio to 30 video streams in 5 mins.

  • monksaru John (@monksaru) reported

    @ThreeUKSupport Hi Laura. It's not, it's through a third party online store. I can get a better deal on the three network anywhere else than through the three store. I've been with three since 2004 and each time I go to upgrade I find it cheaper to go via a third party.

  • steedobson87 スティーブンドブソン (@steedobson87) reported from Derbyshire, England

    @ThreeUKSupport Have you not scrolled up to see the previous tweets I sent? If not let me break it down for you..last phone bill was £133 should be £64 was about a week or so late paying it but I did..had a look and this month's is £133! Absolute b.s I REFUSE to pay it. Is this how you treat you

  • NyaanTV MikMakKat 🎃 ☆ (@NyaanTV) reported

    @ThreeUK are literally the worst and most inefficient phone company every. It's bloody tiring.

  • dogboytwit DogBoy (@dogboytwit) reported

    @ThreeUKSupport Still barely any service??? What’s happening? Not happy

  • DavySedge David Sedge (@DavySedge) reported
