    @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

  • 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

  • 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.

  • 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 .

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

    @ThreeUK network down after I ios update overnight #threedown

  • 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

  • k_stalou Yecats (@k_stalou) reported

    @ThreeUK Yet again I have no network. I will not be staying with three. You are a joke

  • Pseudomorph81 Jonathan Bryce (@Pseudomorph81) reported

    @deanolium @ThreeUKSupport Absolutely. It's almost never the fault of the person at the end of the phone. Having been there I know that all to well!

  • selz_j Selina JS 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇩🇪🇬🇬🏴󠁧󠁢󠁷󠁬󠁳󠁿⚒️ (@selz_j) reported

    @ThreeUKSupport hi, I am still having problems with my mobile broadband connection - there are no issues with the mast in my area anymore but my modem is still saying it's online but won't connect to anything. Is there any chance I can be sent a new one?

  • DeonaElizabeth Deona Elizabeth🤍 (@DeonaElizabeth) reported

    No one should EVER get an account with @ThreeUK @ThreeUKSupport. They are THE WORST network, I’ve called several times each month since last October and nothing has changed. Now when I’m leaving the network within the cooling off period, they’re trying to levy me with charges 🙃

  • lingazzi Marco Lingazzi (@lingazzi) reported

    @ThreeUKSupport I have three accounts with Three one for phone and two for tablets. I need to cancel the two tablet accounts but I don't have the numbers for them how do I get them to cancel contracts Many thanks Alan Duggan

  • dawnee84 Dawn (@dawnee84) reported

    @ThreeUKSupport I did. They said there was a problem with a neighbouring mast. This seems to be a new issue though..

  • ChiHaiDong 驰海东 (@ChiHaiDong) reported

    @ThreeUK are the most annoying company on the planet. Constant sales calls from random landlines and mobile numbers. I've frequently asked the to remove my number from their lists, but still the calls come. I was once a loyal customer, never again

  • MarcusFarran Marcus Farran (@MarcusFarran) reported

    @ThreeUKSupport awful service from three again. My wife bought a new contract with you 1 month ago. She asked support if she could transfer her old number from an existing three account to the new one. Your support said she would need to wait for her old account contact to end.

  • Adamski_Leeds Adam Crossland (@Adamski_Leeds) reported

    @ThreeUKSupport hello, I cannot log into the Three app and have not been able to all day. I need to contact you guys t get my services reinstated and I can’t call 333 so the app was my only choice. Can you help?
