  • 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.

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

    @omnitix @ThreeUK first 3G only network innit

  • richieh Richie H  (@richieh) reported from Caerphilly, Wales

  • 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.

  • 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

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

    @ThreeUK network down after I ios update overnight #threedown

  • elisemarylin éli (@elisemarylin) reported from Barry, Wales

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

    @ThreeUK fix up

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

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

  • stumpy_juk Matthew Jones (@stumpy_juk) reported from Cardiff, Wales

    @ThreeUKSupport network issues in Cardiff..

  • 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.

  • 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

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

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

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

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

  • 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

  • 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

  • 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

  • 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.

  • 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 .

  • 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

Latest outage, problems and issue reports in social media:

  • AndrewD1553 Andrew Douglas (@AndrewD1553) reported

    @ThreeUKSupport I’m already out of contract so on a 30 day rolling term. Does that mean I’ll be charged for roaming 30 days after the effective date? If so, please let me know how I can transfer my number to a competitor network. Only been a customer since 2012 after all !

  • BadgerHUD Rob Perry (@BadgerHUD) reported

    @cjeam @SkyNews @ThreeUK They're a terrible network, you can't even travel in the UK without losing signal

  • ArmouredGoat harry (@ArmouredGoat) reported

    @ThreeUK is about to loose a lot of customers, U-turn on roaming charges, new customers and change of contract customers, so basically everyone at some point. The network is lousy and slow and the phone deals can be had with other providers chargable roaming humour.

  • streboria Benjamin 🏴󠁧󠁢󠁷󠁬󠁳󠁿🇪🇺 (@streboria) reported

    @ThreeUK the main reason I have been a long-term Three customer is being able to use my data allowance outside of the UK without additional charges. Why should I pay extra to use what I’ve already paid for? When my contract ends I will be switching to @O2.

  • hellopoe Adrienne Pitts (@hellopoe) reported

    . @ThreeUK I’ve tried three times to cancel my pay monthly phone contract. I don’t have the password anymore. I’m in New Zealand. Haven’t used the # in over 6 months. Cannot call you. Chat can’t help me. Please for the love of all things just cancel my account.

  • Quak3r72 Simon Leary (@Quak3r72) reported

    @ThreeUKSupport I thought there was a premium on the service for when I was travelling abroad? My apologies for assuming that to be the case. Or have I been with you for that length of time that it has been and gone?

  • MarkBeerstar58 norman tunna (@MarkBeerstar58) reported

    @ThreeUKSupport @DrNik28 Useless **** network

  • kevcaveney KevCav (@kevcaveney) reported

    @ThreeUK just seen the announcement that Three is removing the free roaming. The outstanding bit of three was the customer service and roaming. Looks like a move at contact end 🙁🙁

  • DeanGaryCox DEΛN COX (@DeanGaryCox) reported

    @Coastermitch @ThreeUK Bad business move considering they’re removing the other non EU countries. Luckily I’ll retain EU roaming due to having an earlier contract, but whole point of having 3 was so I could use in USA too, not very pleased 😳

  • Bigfootbull Ian Harrison (@Bigfootbull) reported

    @ThreeUKSupport Very poor service in the CA14 1JX area. The CA15 seems back to normal today
