    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

  • 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

  • pringoli lynda pring (@pringoli) reported from St. Julians, Wales

    @ThreeUK hope network is working correctly now! Hit and miss since yesterday 🤔

  • 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.

  • mindspits Rhys (@mindspits) reported from Cardiff, Wales

    @mythofechelon @TMobile Could be a @ThreeUK issue as their network was down overnight.

  • elisemarylin éli (@elisemarylin) reported from Barry, Wales

    @ThreeUK i literally need my phone to study yet i can't because your phone lines are down, absolutely ridiculous. i will 100% be switching after this, thank God my contract is up.

  • 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

  • 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.

  • x_Gabrielle_x Gabrielle Jenkins (@x_Gabrielle_x) reported from Newport, Wales

    On hold to @ThreeUK possibly the worst phone company i’ve ever encountered in my whole life

  • Killaree4 Ree K (@Killaree4) reported

    Really strange. Ordered an upgrade ipad from @ThreeUK yesterday, supposed to be delivered today and I find out the parcel was requested back by Three. Called them up and they asked for an email of information/proof, which i have provided. Can you help @ThreeUKSupport ?

  • ChaffaSte Ste (@ChaffaSte) reported

    @ThreeUKSupport Yeah. Not good enough. Smarty (owned by three) would give me eu roaming on a rolling contract today. I didn’t expect much by raising my grievance and it looks like I have got nothing. Instead my whole family shall be moving away from three as soon as we can and shall never return

  • Gunnerhappen Ben Harvey (@Gunnerhappen) reported

    @ThreeUKSupport no signal in North Norfolk for the last couple of days, is this going to improve today?

  • Damreyuk73 Damian (@Damreyuk73) reported

    @ThreeUKSupport I do that every time it happens which is very regularly. It always takes ages on the phone and they always try to blame my hub until finally admitting that it's a network issue

  • Paul_Ratty_R Paul Rowland (@Paul_Ratty_R) reported

    @superdrugmobile @ThreeUKSupport Is there an issue in the CW1 postcode area with mast down. Network coverage keeps dropping to nothing since yesterday

  • LuSchmoo Lu (@LuSchmoo) reported

    @ThreeUKSupport I have to turn it off in order to completely access the box. Is there any update on this? I think I direct messaged you a screen recording of the issue awhile ago, that’s when you said you pass this on. Thanks.

  • JohnInman6 JRinman6 (@JohnInman6) reported

    @mwoodgates @chrisguy99 @ThreeUK I have a Tastecard that offers 25% off at CN. I actually went elsewhere and paid full price,as often my local CN needs a damn good tidy.

  • breezy_yehmait Omoyemi Akinbola (@breezy_yehmait) reported

    @ThreeUK you guys must be a joke wanting to rip me of my hard earned money. My phone contract ended and I spoke with your customer rep who gave me a new sim only contract. I did what was required on my part by ringing you before the end of my previous contract. @Ofcom

  • ___kris_______ (@___kris_______) reported

    @ThreeUKSupport any idea when the service in the ne28 area is going to be back up and running properly? My home broadband has been practically unusable for a couple of weeks…
