Latest outage, problems and issue reports in Cardiff and nearby 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

  • 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.

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

    @ThreeUKSupport You have lost me a customer as of today and my complaint is currently with the ombudsman. Your staff and managers are awful!

  • 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

  • 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

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

    @ThreeUK customer service is horrendous

  • 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

  • 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 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..

  • 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

  • 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.

  • 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 😐

  • 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.

  • 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

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

    @ThreeUK I have just had the worst customer service experience I have ever had. My knowledge of your products and services was much better than your staff. Also, TV noise un background made it hard to understand the Glaswegian accent and adviser 2 spoke fast and did not listen 😡

  • 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

  • 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.

  • 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

  • reece_evans Reece (@reece_evans) reported from Weston-super-Mare, England

    @ThreeUK why am I paying for a service that NEVER works at my house - BS494EQ

  • ZakSilverstein Zak Silverstein (@ZakSilverstein) reported

    I have to ask @ThreeUKSupport, I've been offered to send back the IPad Pro in order to cancel the Contract as a special "One Time Acceptation" But I want to confirm that If I do, Does Three Promise to cancel the contract? If so then I'd be open to sending the device back.

  • ZakSilverstein Zak Silverstein (@ZakSilverstein) reported

    @ThreeUKSupport Hello Nathan, Yes, I spoken to Customers Relations Team (CRT) about this and they mentioned as long as the device is in "Good" condition they'd be open to cancelling the contract as a one time acceptation, They mentioned It would cost £975.00 if I was to cancel the contract...

  • mrhaynz Benz Grima (@mrhaynz) reported

    @ThreeUK where is my broadband device? Why is your dpd delivery driver moving mad all over the area? Nearly 3 hours after the time slot and no delivery on the second attempt. Customer service is just a dead concept these days…

  • alextana92 Alex Tana (@alextana92) reported

    @ThreeUK have been experiencing incredibly slow 5G speeds on broadband in Brighton Centre (BN1) for about two weeks, is there an outage or?

  • I_Salute_Cheryl ♡Emily♡ (@I_Salute_Cheryl) reported

    @Abcmsaj @ThreeUKSupport Yeah it keeps counting down from 10 seconds, waste of time

  • DavidGaleUK Derby Dave (@DavidGaleUK) reported

    To anyone considering a move to @ThreeUK / @SMARTYMobileUK mobile network, BEWARE. Very fast on 5G but the service blocks important campaign websites and generates bounce-backs from email servers. No response despite repeated comms to customer support #Misrepresentation #Unusable

  • BRBAndy Andy (@BRBAndy) reported

    @abbeylinegold @virginmedia @ThreeUK Reason I haven’t got rid of them ( again ) is just pure laziness . That’s about to change . Poor connection , poor customer service expensive beyond belief .

  • DGStormtrooper Dan (@DGStormtrooper) reported

    @ThreeUKSupport sent you DM poor coverage for week or so again

  • justjimjams justjimjams (@justjimjams) reported

    Forget 02 Priority get onto @ThreeUK + app logged on no problems checked out in 5 mins! #BUSTED20

  • ReeseHughes Reese Hughes (@ReeseHughes) reported

    @ThreeUKSupport your company has completely messed me up! Ported business number over from O2, promised no loss of service but not working. Customers can't contact me "number you have called is not recognised". My business affected badly because of you.
