3 (Three) Issues Reports Near Cardiff, Wales

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 😐

  • 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

  • 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.

  • SimoneJonesx Simone Jasmine Jones (@SimoneJonesx) reported from Alway, Wales

    Imagine being a @ThreeUK customer with 2 contracts for years on end and being told to find another service provider because they can’t fix the masts in my area and then refuse to refund what I’ve paid off this mobile or even pay my upfront cost for my next phone 😡 #scabs

  • 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

  • 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

  • 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.

  • 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 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.

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

    @ThreeUKSupport no mobile internet signal in Swindon Wiltshire at the moment, got cut off about 90mins ago, done all resets so phone all good! Any issues showing with you?

  • kierawatchestv kiera 💫 (@kierawatchestv) reported

    @ThreeUKSupport He has a Google Pixel 4a- he's tried manually changing it but it doesn't pick up any networks, just continually says 'no service'.

  • peakedspeak Rowena ⚢ 🦉🦖 (@peakedspeak) reported

    @HerGameToo @ThreeUK That’s a man. He’s not even trying. Don’t be stupid.

  • andrewwright2 Andy Wright (@andrewwright2) reported

    @ThreeUK my connection has been switched off. No explanation. No arrears on account. People in shop can’t help. Apparently the team overseas that could help knocks off at midday UK time. Not much use. It’s now preventing me from accessing banking etc. anything you can do to help?

  • XantheClay Xanthe Clay (@XantheClay) reported

    @seb_cheetham Yup same issue today - @ThreeUKSupport worth mentioning this on the connection page? Chrome works, Safari doesn’t

  • JonnyB289 Jonny (@JonnyB289) reported

    @ThreeUK I upgraded my phone yesterday and got a confirmation email and a text saying congratulations on upgrading and it said my phone is due to be delivered today but didn’t get a text this morning with tracking information. I rang up three and used chat but didn’t help.

  • razvan_radu_4u razvan radu (@razvan_radu_4u) reported

    Same s..t @ThreeUK network!!!! @ThreeUK you are improving: from bad internet connection to NO internet connection at @HeathrowAirport

  • Danieloopspedro Dan Stevenson (@Danieloopspedro) reported

    @ThreeUKSupport So I've lost a week on a data pack with no warning or heads up? What a waste of money, I understand issues)problems but not even a message to warn customers is poor form

  • nickmward Nick Ward (@nickmward) reported

    @njamie32 @ThreeUK its awful. I am thinking of moving for the first time in 16 years.
