  • 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 .

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

    @ThreeUKSupport network issues in Cardiff..

  • 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.

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

    @ThreeUK i literally need my phone to study yet i can't because your phone lines are down, absolutely ridiculous. i will 100% be switching after this, thank God my contract is up.

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

    @ThreeUK fix up

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

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

  • 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.

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

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

  • 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 😡

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

    @omnitix @ThreeUK first 3G only network innit

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

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

  • 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.

  • 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.

  • 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

  • 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

  • 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.

  • 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!! 👎👎👎

  • 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!!

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

    @ThreeUK network down after I ios update overnight #threedown

  • jokeoil Coyle (@jokeoil) reported

    @ThreeUK Terrible customer service. Can't get through to staff to discuss iPhone you have sent me that can't be set up.

  • Bokabecks Bryan (@Bokabecks) reported

    @ThreeUKSupport Signal keeps dropping west of Scotland, just cuts right off, was in Greenock and now in Glasgow and same thing.

  • IndyLive_Isles 🏴󠁧󠁢󠁳󠁣󠁴󠁿≋𝕀𝕤𝕝𝕖𝕤≋𝕄𝕖𝕕𝕚𝕒≋ (@IndyLive_Isles) reported

    @VodafoneUK All I hear is, not enough folk live there, we don't care about the area. Stupid companies, need to learn: If a tourist sees me on my mobile, esp if I'm on data & is amazed, I'll say to use @ThreeUK & @EE, not #Vodafone & consider contract swaps.

  • DawudMarsh Dawud Marsh Ⓥ (@DawudMarsh) reported

    @ThreeUKSupport Does that mean you’ve decided not to follow up our complaint that our internet is rubbish? Just leave us to suffer with it?

  • bad_amberlouise Amber Louise (@bad_amberlouise) reported

    @ThreeUKSupport Are the N Dubz pre sale tickets not working for Manchester? Everytime I tried to buy tickets it said not available

  • DawudMarsh Dawud Marsh Ⓥ (@DawudMarsh) reported

    @ThreeUKSupport So, @ThreeUKSupport I contacted Iceland on social media, they quickly agreed a refund and issued it to us. You guys, started to follow up and now nothing despite us tweeting what poor internet we have to put up from you. And you don’t respond at all.

  • ernmander ernmander (@ernmander) reported

    @simon_harper @ThreeUKSupport It’s annoying, there must be something proactive that can be done. Blocking the numbers doesn’t solve the issue.

  • smllgrnstudio Nick PrEditor (@smllgrnstudio) reported

    @ThreeUKSupport Happened in Canada, Luxembourg and Germany. Didn’t receive a phone signal. Find Wi-Fi to chat to 3. But lose the chat every time you go to settings. And re-queue. Flawed chat system.

  • ScottOR09 Scott O'Rourke (@ScottOR09) reported

    @ThreeUK anyone having trouble getting tickets on pre sale, literally on the website at 10am the page loads but says no tickets??

  • ukvote15 Election (@ukvote15) reported

    @ThreeUK still taking money from my bank account over a year after I cancelled my phone contract. This must stop now @Ofcom can you help put a stop to this wholesale theft?
