  • 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

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

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

    @ThreeUK fix up

    @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

    @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 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.

  • 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.

  • 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 😡

  • 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

    @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.

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

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

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

  • CityFarmSystems City Farm Systems (@CityFarmSystems) reported

    @Xero @ThreeUK @ThreeUK's broadband connectivity in our temp facilities has been so bad this year they are damaging our devices. Strangely only Xero issues yesterday - couldn't find your servers whilst other websites were fine. Once found no notification came on O2 mobile. Now sorted.

  • GemRedford_FMN Gemma Redford (@GemRedford_FMN) reported

    @OllyM07 @ThreeUK @ThreeUKSupport Mines been like this and strangely a couple of months ago, black holes appeared where my phone doesn’t work at all. I’ve not had this problem before with 3. X

  • lilliJSingh LilliJSingh (@lilliJSingh) reported

    @ThreeUK COME ON! went for upgrade..ended up having to call loads to get my number sorted! Started me a business contract without explaining the issues of moving over number and now I have no data on my now fixed contract

  • docta_liam Liam Hudson (@docta_liam) reported

    @ThreeUKSupport after comically unstable broadband connectivity with my 5G hub I followed your instructions and reset. I’ve gone from 40MB/s to 5MB/s download. Help! I have 5 bars 3/5G connection. Is there any settings to adjust ?

  • stupearson78 Stu Pearson (@stupearson78) reported

    @ThreeUKSupport been having issues last few days in DN16 area with both internet and call signal, seems to drop out and sometimes comes back with a device reboot, got a few friends having similar issues, is there some work being done somewhere?

  • ChrissyKinsella Chrissy Kinsella (@ChrissyKinsella) reported

    Productive lunchtime, changed mobile phone providers after 20 years from @VodafoneUK and changed broadband providers after 12 years from @virginmedia, moving both accounts to @ThreeUK for MUCH CHEAPER monthly cost and apparently far better service all round. Win.

  • michbouic Michelle Bouic (@michbouic) reported

    @ThreeUKSupport have you had anyone report issues with their 3 service when using the new Galaxy Flip3? I thought it was a network issue but now am wondering if the phone is the problem...

  • GamerForBritain GamerForBritain (@GamerForBritain) reported

    Never use @ThreeUK they are the worst. Today they threatened debt collectors. But the money that is owned is on a number I have never had and they are contacting me on my acutal number too. They said its now with their fraud team but I have had no email or anything to show that.

  • ChrisBurgess72 Chris Burgess (@ChrisBurgess72) reported

    @pjtiler @ThreeUK Already pay a stupid amount per month and that’s pushed it to the ridiculous
