Latest outage, problems and issue reports in Cardiff and nearby 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 .

  • 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

  • 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

    @ThreeUK customer service is horrendous

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

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

  • 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

    @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.

  • 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.

  • 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

  • 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.....

  • 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

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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

  • 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

  • pringoli lynda pring (@pringoli) reported from St. Julians, Wales

    @ThreeUK hope network is working correctly now! Hit and miss since yesterday 🤔

  • 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

  • elisemarylin éli (@elisemarylin) reported from Barry, Wales

    @ThreeUK i literally need my phone to study yet i can't because your phone lines are down, absolutely ridiculous. i will 100% be switching after this, thank God my contract is up.

    @ThreeUKSupport Good job I never contacted your ThreeUkSupport account for help, ah wait..... #whatsthepoint

  • Lil_Shroombit R. Hoye (@Lil_Shroombit) reported

    Anyone's signal and Internet worse after the Three/Vodafone merger? @ThreeUKSupport @VodafoneUK

  • AlexJive Alexander Kenneth Martin Douglas (@AlexJive) reported

    I thought @ThreeUK ‘s reception was supposed to improve now they have merged with @vodaphone. It’s still awful.

  • dmbird946 Digital Power Promotions (@dmbird946) reported

    @ThreeUKSupport internet on phone is still down 5th day your service is terrible and customer service is worse they are abroad and don't care that your internet is not working they are rude. This is stressful when I'm supposed to be relaxing after work £36 a month I want a refund

  • rock_dodd Rock Dodd (@rock_dodd) reported

    @ThreeUK, though ****, was nothing like as **** as @VodafoneUK . Today, I learn, they have merged. ****! Now I must leave the country if I want a decent mobile phone service provider

  • grantdotdev Grant - 🧑‍💻 (@grantdotdev) reported

    Have you ever seen a company send your full bank details in plain text within the content of an email ? This is what @ThreeUK just did to me and it’s very troubling. I’m awaiting their customer service team to contact me tomorrow to rectify this huge oversight in their security

  • Jack113948 Jack (@Jack113948) reported

    @ThreeUKSupport I have now been without 4G for a week. 4G bars on phone at full but no access to apps or browser. Customer service dont seem to know what they are talking about. What am I actually paying for?

  • mcginty46 Mcginty (@mcginty46) reported

    @jimmysunny85 @ThreeUK Last few days my signal has been shite..now i know why..thank god i'm sim only..will be off soon..

  • seanpaulguitar Sean Redmond (@seanpaulguitar) reported

    looks like im done with @VOXImobile unless they can sort a few things out. Pricing, speed, and quite a few more issues, gave @ThreeUK unlimited a try and its cheaper, several hundred megabits faster... Anything you plan to do to speed things up Voxi?

  • outwrite 𝐋 𝐄 𝐄 ™ (@outwrite) reported

    Shockingly slow data speeds again from @SMARTYMobileUK / @ThreeUK Sad, because it's been reliable enough for the past couple of years... Time to find an alternative I think.
