  • 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!! 👎👎👎

  • 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 !

  • 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.

  • 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.

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

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

  • 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

  • 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.

  • 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

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

  • 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.

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

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

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

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

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

  • 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 😡

  • 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.

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

    @ThreeUK fix up

3 (Three) Issues Reports

Latest outage, problems and issue reports in social media:

  • SteveMeek82 Steve Meek (@SteveMeek82) reported

    @HuaweiMobileUK I need some help with my AI Cube, @ThreeUKSupport have advised I contact you. When multiple IoT devices are connected the router lags and other devices often get disconnected. Rebooting helps for a day or so then need to reboot again.

  • SteveMeek82 Steve Meek (@SteveMeek82) reported

    @ThreeUKSupport My AI Cube has an issue where when you connect more than half a dozen devices to it some devices will lose network connectivity or be disconnected. This affects intranet traffic and is not signal related. 2nd line said they can't help as it's not a 3 issue. Help.

  • GBlankcanvas67 James black (@GBlankcanvas67) reported

    @ThreeUKSupport It's not the point of being offered anything it's the fact that your company is blatantly lying by first saying it fixed and engineers saying the same when it's not then being told again there is still a problem when I report it 3 weeks after that and for it now to be going 1/2

  • harrietjonesmus Harriet Jones (@harrietjonesmus) reported

    @ThreeUKSupport It's still not working :(

  • kilgourrebs REBECCA. (@kilgourrebs) reported

    Anyone in ML7 should avoid @ThreeUK. There’s been a known issue where you’ve either got no service or it shows as 3G but still doesn’t work since 11th Nov. @ThreeUKSupport are no use for it either. Poor show.

  • vesi_xoxx vesi ✨ (@vesi_xoxx) reported

    @ThreeUKSupport I have tried it already and it does not work at all. I have tried with all available networks and each time it says “not registered with the network”

  • strider_636 D_Strider 🇬🇧🌹 retweet pinned tweet (@strider_636) reported

    @ThreeUKSupport There’s been no upgrades done to the mast since January 2020 as I remember I saw it on your website. I was at my nans over Christmas and the congestion was so bad we couldn’t even make calls on our mobiles. Stop leaving small towns out from your network upgrades. It’s awful.

  • vesi_xoxx vesi ✨ (@vesi_xoxx) reported

    @ThreeUKSupport hello, I’ve been outside of the UK for a year now and don’t know when I would move back - at first my 3 SIM worked well, however after my contract ended and I switched to PAYG, I’ve had absolutely no service. After speaking to your colleagues through livechats 1/3

  • wwfc_dave Dave (@wwfc_dave) reported

    @ThreeUKSupport Thanks for your reply. In general, what do customers do to connect extra routers to expand wifi? 5G is always best on window sills, which is worst for WiFi coverage so this prob must be common. Thx.

  • SteHuthwaite Stephen Huthwaite (@SteHuthwaite) reported

    @ThreeUKSupport what is happening with your service,I live in the ol16 area and my service is rubbish, when I moved here 4 years ago it was ace,full 4 bars of reception service,and 4g that would achieve 70mbs speed,since the 5g was connected everything seems to have gone to ****!
