    @ThreeUKSupport network issues in Cardiff..

  • WildthingJ74 Johnathan Williams (@WildthingJ74) reported from Cardiff, Wales

    @samboc86 @hockey_laura @Apple @ThreeUK I hate change and I'm sure they bank on being being apprehensive about it. I'm never going back to them

  • ClareO74 Clare Owen (@ClareO74) reported from Cardiff, Wales

    @ThreeUK Not great service! Look after your loyal customers #loyalcustomersmeannothing 😡

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @JohnDubyaUK @ThreeUK Yeah they’re all in such a rush to get 5G out, they just seem to have given up on trying to get 4G sorted out. At least show me I’ve got a crap signal, don’t pretend it’s all full speed and awesome.

  • KrisheleG Krishele Guzman (@KrisheleG) reported from Cardiff, Wales

    Horrible T&Cs usage by @ThreeUK and #Wuntu on their Google Play offer. Tricked me into charging my bill instead of using the offer!!

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @jaybee_ms Moved to them last month. Advise against it. Data service has been awful. Wish I'd never moved provider. Tried all the main providers and 3 is by far the worst #threeuk #crap

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport This was in CF83 1XP and it’s been terribly slow for months now.

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport Been through this, you won’t check as it’s a business account and the business team never follow up. 2 years ago Caerphilly had around 40mb down now it’s about 4mb down and no one there seems bothered.

  • TicketTattle Andrew Thomas (@TicketTattle) reported from Cardiff, Wales

    @omnitix @ThreeUK first 3G only network innit

  • KrisheleG Krishele Guzman (@KrisheleG) reported from Cardiff, Wales

    @dlever21 @ThreeUK My problem was they added a new condition this time that said if you haven't used it since January. but @ThreeUK ran the offer in May and I used it then. Guaranteed they caught LOADS of people out 😡

  • SueLidds Susanne Liddeatt (@SueLidds) reported from Weston-super-Mare, England

    @ThreeUKSupport They have absolutely messed the whole thing up! I have no 4g, no phonecall facility and when I check the plan on the app I seem to have reverted to the old one. Each ‘chat’ tells me it will be ‘perfect and not to worry’ total nightmare! I’m paying for an invisible service

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport No improvement after a restart and I tried 3 different phones so I know it’s not my phone. The phone is on 3G most of the time anyway and it is around the same speed as 4G. The signal is absolutely terrible.

  • Bubwal Ade (@Bubwal) reported from Cardiff, Wales

    @RobBruceK @ThreeUK @O2 @EE @VodafoneUK No awful. Just spent 5 days with no data/calls due ti Insufficient bandwidth. My family and friends who were with O2/BT/Vodaphone had no problems. Worst ever. So regret leaving previous provider last month. Their coverage checker is inaccurate too

  • Moe3k9 C-Note (@Moe3k9) reported from Cardiff, Wales

    @ThreeUK fix up

  • SueLidds Susanne Liddeatt (@SueLidds) reported from Weston-super-Mare, England

    @ThreeUKSupport This mornings ‘live chat’ seems to have solved the problem. I will wait to see if I no longer get two contract bills . I live in hope !

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

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport They said wait a week and try again, and it’s still horrendously slow.

  • MartynPreece79 Martyn Preece (@MartynPreece79) reported from Cardiff, Wales

    @ThreeUK great if you have no issues, as soon as there’s a problem they give all the bull!! 👎👎👎

  • oxWelshElisexox 🏴󠁧󠁢󠁷󠁬󠁳󠁿Welsh Elise🏴󠁧󠁢󠁷󠁬󠁳󠁿2k (@oxWelshElisexox) reported from Cardiff, Wales

  • MK__C MK (@MK__C) reported from Barry, Wales

    @lloydhollett @ThreeUK @O2 Sorry Lloyd but #3Mobile use the same network as #o2. Hopefully the customer service will be better though!

  • ConnerMcNamara Conner McNamara (@ConnerMcNamara) reported

    on calling, I was advised to accept the order when it arrives and then send it back, or to cancel completely. I am now in touch with complaints who are trying to put me to sales for a new product without acknowledging my concerns? What is this all about @ThreeUK

  • DR_McViz Dr McViz (@DR_McViz) reported

    @ThreeUK Network completely down in G33 6 area following a mass power cut. No facility to report it on your website!!!

  • poppycocteau Johnny Thunders (@poppycocteau) reported

    @ThreeUKSupport @ThreeUKSupport is that humour? The issue existed for months prior to me talking to the 'team' - my image of PM was from back April this year and it has persisted until today, so 7 months have passed since being "passed on" - how was tweeting you of any help whatsoever!?

  • speedyred711 Ian (@speedyred711) reported

    The Internet on @ThreeUK lately has been seriously seriously seriously bad

  • RDug56 RangersDug56 (@RDug56) reported

    @rob3047 @ThreeUK I use a mifi on three (without an antenna) , tbh I get better service just using my iPhone on Tesco (o2) 99.9% of the time.

  • danny_lingham danny lingham (@danny_lingham) reported
