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

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

  • 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 .

  • 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.

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

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

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

    @ThreeUK fix up

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

    Imagine waiting 30 odd minutes for the upgrades department to then be put to customer service who then says yeah upgrades is down at the moment @ThreeUK 🙃 Legit wasted my time

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

    @EnglishPhoebeX1 @ThreeUK @ThreeUKSupport **** mines been cutting out on calls but not no network

  • 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

  • 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

  • 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!! 👎👎👎

  • 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 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.

  • 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.

  • 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

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

    @omnitix @ThreeUK first 3G only network innit

  • 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.....

  • 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.

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

  • katlin_holden katlinnnn👩🏻‍🦰 (@katlin_holden) reported

    @ThreeUK sort ya signal out man

  • Thompa_1972 Alan Thompson (@Thompa_1972) reported

    @ThreeUK can you please explain why you took a £65 early redemption fee for a no longer needed contract, failed to cancel the contract then charge for 3 more months including £10 for not paying by dd before finally ending the contract?

  • davidball1978 David Sutton-Ball 🏳️‍🌈🌈 (@davidball1978) reported

    My advice people is stay away from @ThreeUK. Service has been appalling for the last 2 years and despite being a customer (until recently) for 6 years no one will help me resolve a complaint that started before I left them. Horrendous customer services.

  • HylandGabrielle gabrielle (@HylandGabrielle) reported

    @ThreeUKSupport I have now spoken to two of you members of staff. Both who were more concerned about my payment of £127 rather than the issues I had raised to them. I asked if I could pay it in two separate payments so I didn’t struggle in the run up to Christmas...

  • Thompa_1972 Alan Thompson (@Thompa_1972) reported

    I have spent hours on line to your customer services being ensured that I won't be out of pocket but that is a complete lie. I can't wait to run out my contract so I can leave your network - as well as friends and family who I foolishly recommended go with you. @ThreeUK disgrace

  • newworldruler Daniel Martin-Corben (@newworldruler) reported from Portsmouth, England

    @SafeT @virginmedia @ThreeUK I think it's service work too, I understand things have to be done, but you'd think they'd at least warm me and I could have made other plans.

  • planetf1 Nigel Jones (@planetf1) reported

    @SMARTYMobileUK @ThreeUKSupport They eventually replied but still not getting much sense . Since tried two more locations and network is equally shockingly bad. Asked about cancellation yesterday and again today. Query not recognised yet. Abysmal service

  • SafeT SafeTinspector: not actually safe nor an inspector (@SafeT) reported

    @newworldruler @virginmedia @ThreeUK Different country, same probs. For me it’s Xfinity cable internet down and tethering with Verizon Wireless

  • DrewWil90248865 Drew Williamson (@DrewWil90248865) reported

    @ThreeUKSupport Every time I try that it doesn’t work, it just says please try again later. This needs to be sorted ASAP before I log a formal complaint. I have been with 3 over 10 years now

  • A_J_Murphy1987 Here Be Dragons (@A_J_Murphy1987) reported

    @NathanTrout @Three_Is_Broken @ThreeUKSupport Have you tried turning it off and on again? Maybe you have particularly thick building walls? Maybe your SIM is faulty? -- Usual Three excuses for their useless network.
