  • 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

  • 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

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

    @ThreeUKSupport network issues in Cardiff..

  • 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

    @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.

  • 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.....

  • 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.

  • 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.

  • 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

  • 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

  • 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.

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

    @ThreeUK fix up

    @ThreeUK your customer service is shocking.

  • BecklesCake92 Becky Moss (@BecklesCake92) reported

    @ThreeUKSupport for the last year barely been able to get 4G, internet data is hit and miss on 3G. Last 4 days it’s been ridiculous, constantly ‘no service’. Whyyy?!?

  • omar192122 Omar Farooq (@omar192122) reported

    @ThreeUKSupport Well that's your issue, I have logged a complain with the ombudsman

  • _DistortedSmile Emski (@_DistortedSmile) reported

    @ThreeUKSupport it's now been three months with no active SIM, I still cannot use my phone off the Wifi & I've can't face being told the old story by the 8,976th live-chat operator. Any danger of my complaint being resolved & fixed?

  • MacDoodle8 Gemma MacDonald (@MacDoodle8) reported

    @ThreeUKSupport Really poor 4G mobile broadband service lately. Are there local issues in the KY11 4XD area? Been poor for almost a week. Have reset our routers, but no improvements.

  • andrewscorgie Andrew Scorgie (@andrewscorgie) reported

    @ThreeUKSupport I've been with very weak signal all day here in the KY8 postal code area, was the same yesterday afternoon too. Is that cell tower dying again in this area? seems to happen a bit too often

  • gem_scott3 Gem Scott (@gem_scott3) reported

    @ThreeUKSupport Jenn I tried webchat. They couldn’t help me because I can’t remember the memorable word on the account. Really no point having the same conversation again?!
