  • kneeara Niara (@kneeara) reported from City of London, England

    @ThreeUKSupport I found out the reason , for some reason you deactivated my sim card before I received the new one which was being sent to fix my network issues. It meant no one at work could reach me all day and I could not make any call.

  • charliemfc Charlie (@charliemfc) reported from Bromley, England

    @ThreeUK @SamsungUK Advertising 5g phones when your already late 5g network is nowhere to be seen yet 🤔

  • PelhamB PelhamB (@PelhamB) reported from Croydon, England

    @ThreeUK you are literally the most incompetent mobile network. I returned a home signal box to you on Dec 18th, have provided proof of this TWICE by email and you have still sent me a bill for £75. This is the second time your Norwich centre have lost a returned signal box

  • nshancock Nick Stephen (@nshancock) reported from City of London, England

    I’ve just spent 2 weeks in the USA using the @ThreeUK GoRoam and had perfect signal and fast 4G the entire time. I come back the the U.K. and revert back to the awful slow ‘4G’. Sort it out @ThreeUKSupport - you used the be great. Service in my own country is crap nowadays!

  • ValentineMick Paris Preeeerb (@ValentineMick) reported from Islington, England

    @ThreeUK your network has been such a piece of fkn shit this past month +... be better

  • RuthElleson Ruth Elleson (@RuthElleson) reported from Camberwell, England

    @hollieenelsonn @BenThapa82 @ThreeUK Appreciate this doesn’t solve the problem, but I’ve turned mine onto 3G only a few days ago and it works fine for most things.

  • pmw_77 Pauline Wardle (@pmw_77) reported from Stratford, England

    I thought network coverage in London would be first class but really struggling inside most buildings. Is there an issue @ThreeUKSupport

  • BenFisherCT Ben Fisher (@BenFisherCT) reported from Islington, England

    @efjaebe @ThreeUK EE customers have issues too. All networks have problems in dense areas where a lot of users are demanding higher levels of data than ever before.

    @ThreeUKSupport hi there. I cannot use any data on my phone when I am located at work in EC4M 7AW despite phone saying I have a reasonably good 4G signal. Seems to be fine elsewhere in London though.
