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

  • 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

  • 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.

  • 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

  • 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

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

    @ThreeUK customer service is horrendous

  • 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.

  • 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

  • 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.

  • 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

  • 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

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

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

  • 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

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

  • 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.

  • GetMeAManager Don the Trumpet (@GetMeAManager) reported

    @MathewRead @ThreeUK Are you a Three Business customer?

  • FumbertZagaza WorldBawse 🇯🇲🇯🇲🇯🇲 (@FumbertZagaza) reported

    @Lord_Oke @ThreeUK Grave mistake, complain enough about the rubbish service and you might be able to get a little taken off your bill.

  • Ajaddmum ashlee (@Ajaddmum) reported

    @ThreeUK There’s still an issue. On the 3rd day now. Can send texts but not receive them!! Can you get back to me ASAP!

  • DJSmithTech David Smith (@DJSmithTech) reported

    @ThreeUK absolute disgraceful customer services and totally useless. Can’t even supply a phone.

  • davidgood89 David Good (@davidgood89) reported

    @SRoofy @ThreeUKSupport Yeah I am. It just has wobbles a lot more than it used to. But to be fair I do think the router is also **** so doesn’t help. Rebooting often helps but then I do sometimes have to re set connection on my iPhone. It’s weird. My works been going on months. Stil usable overall but

  • LoweIanlowe1970 Ian (@LoweIanlowe1970) reported

    @ThreeUKSupport I’ve been a loyal customer and I’ve 3 separate contracts with you for my phone, pocket WiFi dongle and sim only for my iPad, I will cancel the lot !

  • PughGlobal Pugh Global (@PughGlobal) reported

    @ThreeUKSupport I have had to set my Virtual number to go to my Three Mobile and GiffGaff; even today GiffGaff was passing more calls to me than my Three mobile, so the issues were still active until at least 18:00 today.

  • davidgood89 David Good (@davidgood89) reported

    @SRoofy @ThreeUKSupport @SRoofy in genera the service is not as good as it was. We use 4g for internet cos of no fibre. There’s fibre here now but they haven’t approved our connection so stuck with three for now. When it’s good it’s good but lately it’s bad
