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

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

    @NathanWyburnArt @Apple I’m having a similar issue and @ThreeUK won’t do anything about it. They told me to download some app which won’t help anyway as it’s unknown caller. I think next step is I’ll be forced to change my number 😐

  • 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.

  • 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

  • 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

  • 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 .

  • 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

  • abbie_hunt abbie (@abbie_hunt) reported from Cardiff, Wales

    @ThreeUK I had to change my data to ‘3G’ as advised from your in store staff, because the network is so slow atm.

  • 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 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.

  • 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

  • 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..

  • 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

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

    @ThreeUK customer service is horrendous

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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.

  • 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 ..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.

  • 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

  • sidusTanotus sidusTanotus (@sidusTanotus) reported

    @ThreeUKSupport my mobile broadband internet has been really slow in the past week. Speed is consistently under 5mbps. Not great when you’re working from home. Could you take a look pls. It used to be faster and now every click takes 1 -2 seconds to take effect.

  • gaelruth1 Gael Ruth (@gaelruth1) reported

    @ThreeUK when is service going to be resumed?

  • PlugNTweet Michaël Nass (@PlugNTweet) reported

    Does it applies over LTE ? Your tax is so unclear, the only thing I get is the price! Am I allowed to watch @ptcomedy videos on YouTube using a non-UK VPN outside the accommodation without paying that tax via @ThreeUK’s 5G network? Your FAQ does not give answers. @tvlicensing

  • Issy_beex Issy (@Issy_beex) reported

    @ThreeUK can you please help, my data isn’t working even though I have the unlimited data plan.

  • xchloeevans chloe (@xchloeevans) reported

    I’m really getting sick now of having no signal no 3G or even 4G £65 a month for what! it’s been like this for weeks now😠😠😠 @ThreeUKSupport

  • ChudMoss Chud Moss (@ChudMoss) reported

    @ThreeUK my mum has been experiencing issue making and receiving calls for few days now. She gets this automated message "You can no longer dial 153 from your Three handset. Please redial using 118 313 to connect to the Three international directory service." What’s going on pls?

  • hidinginthevoid a sentient riley (@hidinginthevoid) reported

    @ThreeUK why the hell in the app when I go to sign in, is the password field set to show the password by default instead of hiding it?! I see the little eye icon, but by default hide the password! Seems like this should have failed basic testing / security requirements

  • HarrisonKent1 Harrison (@HarrisonKent1) reported

    @ThreeUKSupport Seems to be working now, I had no 3G coverage at all for a few hours but I have full signal again.

  • amii_elliott Amii Elliott (@amii_elliott) reported

    @ThreeUKSupport Hi, I’m using a iPhone 13 pro and he has a iPhone 12 Pro Max. Both updated etc. seems to be sooo in and out for example in one street I get barely any signal then in the next road I’m getting 5g 😬

  • MarcusRonchi Marcus Ronchi (@MarcusRonchi) reported

    @ThreeUKSupport Many time. I have sent the details via direct message. The thing is, no resolution for this case till now!
