  • 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

  • Dariogutier Darío Gutier (@Dariogutier) reported from Cardiff, Wales

    @ThreeUKSupport Is the same whit whatever I do. Every area I’m going specially when is crowded around me. I have changed SIM cards, phone and the problem is still here

  • AnnaB_Cdf Anna Brzezinska (@AnnaB_Cdf) reported from Cardiff, Wales

    Just came back from North Wales and thanks god I have a sat nav & sos button in my @MercedesBenz as otherwise my journey in the morning would involve searching for an actual road map since @ThreeUK was down, so no service nor data during 4h journey from Cardiff 👎😑🙄 #threedown

  • 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 .

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @NathanWyburnArt @Apple I’m having a similar issue and @ThreeUK won’t do anything about it. They told me to download some app which won’t help anyway as it’s unknown caller. I think next step is I’ll be forced to change my number 😐

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

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

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DJAshBash @ThreeUKSupport @VodafoneUK @ThreeUK I am also on Vodafone. And I would agree they now have overall a formidable network But they have less bandwith 5G than Three..50mHz as opposed to 140mHz so when Three eventually launch 5G 5G it'll be interesting how it all pans out.

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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.....

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DJAshBash @ThreeUKSupport ..a new chunk of 4G 1500mHz aka Ban.d 32. When they're actually commissioned the Three network has huge potential to deal with all these issues virtually overnight. Sadly they don't communicate the cause and ther solutions very well hence disappointed customers.

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

    @ThreeUKSupport Worst company i’ve ever encountered. No wonder why your basically failing as a company

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @DJAshBash @ThreeUKSupport I'm a Three user and have had experience of both good and bad network in and around the Cardiff area. What Three are stating is true but it's taking longer than they planned originally. Three have the largest 5G bandwidth allocation of all the UK networks plus they also have..

  • 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

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Have been with @ThreeUK for years and always been very happy with service. However since renewing to a 24 month contract and 5G getting turned on, my service has been absolutely terrible. Terrible or no 3G/4G, calls cutting out or failing. 1/2

  • Dariogutier Darío Gutier (@Dariogutier) reported from Cardiff, Wales

    @ThreeUKSupport Yeah and the problem was still there, my phone was changed because apparently was the phone and the problem is still here! It’s been 2 years contract in hell!! I can’t wait to finish it

  • 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

  • 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.

  • MisCatD Cat 🖤 (@MisCatD) reported from Cardiff, Wales

    @ThreeUK customer service is horrendous

  • christianfclark Christian Clark (@christianfclark) reported from Cardiff, Wales

    @ThreeUKSupport Yes I usually switch between when my 4G struggles. My calls have been dropping and not working properly too though in a variety of locations.

  • 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

  • samtobo1 Sam Toboggan (@samtobo1) reported

    @ThreeUKSupport I just called and not very happy. I’ve waited 4 days, 2 working days, I confirmed today and now it’s tomorrow. I’m travelling all day. So I’ll be without a phone as I could lose signal at any moment. Ridiculous. Not a good start.

  • Rina_M2020 Rina M (@Rina_M2020) reported

    Why do I always end up with the worst service providers ! Why why why @ThreeUK @ThreeUKSupport And they don’t answer my call either !

  • RalphNe32269576 Ralph Nelson (@RalphNe32269576) reported

    @ThreeUK Just received new router. No sim card, was told wired connection would work - it doesn't. I wish to return it and cancel contract. Do you have the correct number plz?

  • suzanne_000 suzanne allsopp-morgan (@suzanne_000) reported

    @ThreeUKSupport Hi Kirsty I have tried to use this line of help from three but not been successful. please help me

  • suzanne_000 suzanne allsopp-morgan (@suzanne_000) reported

    @ThreeUKSupport this has been going on for nearly 6 months. I have one contract with 3. please help as I am Worried I will incur overdraft charges with my bank

  • northern_grumpy GrumpyNorthernGeezer (@northern_grumpy) reported

    @ThreeUKSupport Well, todays the day that the 3 network team said work would be complete and normal speed internet restored. nPerf full test gave up on the streaming test. Couldn’t even start a 720 video never mind a 1080 Average spd 1.47mbps. Useless. Time to move provider.

  • hossuk HossUK (@hossuk) reported

    @ThreeUKSupport Post Code BA14 7EY. I've had mostly no service since Saturday evening. Service status check says engineers working on masts. When is work due to complete?

  • fromgirders Kelly (@fromgirders) reported

    @ThreeUKSupport I want to cancel my contract on the day the minimum term expires (17:9:22). I understand 30 days notice of cancellation is needed. If I give more than 30 days notice, is it correct I’ll be charged, even though I am not actually leaving my contract early?

  • thomasmccully Tom McCully (@thomasmccully) reported

    @ThreeUKSupport my phone doesn’t allow me to make calls and says “your service does not allow access to this number” can someone help me out?

  • emkwan EMKWAN (@emkwan) reported

    @ThreeUKSupport It’s related to my second sim. I can drop you a DM with the number. When I login via the app or website it’s not allowing me to update data package even though the date has expired.
