  • 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

  • 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

  • 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

    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

  • 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.

  • 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 😐

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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

  • 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

  • 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

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

  • 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.

  • 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.....

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

    @ThreeUK customer service is horrendous

  • 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

  • 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.

  • 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 .

  • 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.

  • abbie_hunt abbie (@abbie_hunt) reported from Cardiff, Wales

    @ThreeUK I had to change my data to ‘3G’ as advised from your in store staff, because the network is so slow atm.

  • ScottPettifer Scott Pettifer (@ScottPettifer) reported

    @ThreeUKSupport I Sent the details as requested via DM, as yet not heard back, I still have really bad signal strength and not able to use my phone for calls. This is a perfect example of extremely bad customer service, why should I pay you for a service that you are not providing....

  • SkinBossBoyd 𝙎𝙠𝙞𝙣𝘽𝙤𝙨𝙨𝘽𝙤𝙮𝙙 (@SkinBossBoyd) reported

    Yes @virginmedia broadband IS down across Greater Manchester this evening. Since about midnight...😧 Switched over to my mobile 4G connection with @ThreeUK and the top download speed is a pathetic 0.43 Mbps!

  • jinnbuster jinnbuster (@jinnbuster) reported

    Actual thieves @ThreeUK @ThreeUKSupport Wasted 14 years of my life giving money to this garbage company. Save yourselvesssssssssssssssssss

  • jb68 Jordan Black (@jb68) reported

    @ThreeUKSupport the 4G signal has been bad on IV306NG. The last few days. Usually get 100mbps+ but it’s been under 1 and been unusable.

  • k8_st8 Katie staight (@k8_st8) reported

    @ThreeUKSupport Was given unlimited data via @educationgovuk to support my children's home learning but got a message saying I'd reached the limit. Contact you via chat - got cut off after 40 minutes. Was then told we'd need to upgrade to sort the problem. What's going on??

  • 3zi090 J Peter (@3zi090) reported

    @ThreeUKSupport I received a text. I was never spoken to by the complaints team.

  • jinnbuster jinnbuster (@jinnbuster) reported

    @davidchalliday @ThreeUK Hi David. I've been a customer with Three since 2008-ish. If you are still within your timeframe for leaving Three without having to pay an early termination fee, I would encourage you to save yourself from this garbage company ASAP

  • AmeliaRoseTighe Amelia-Rose Tighe (@AmeliaRoseTighe) reported

    @ThreeUK I’ve been trying and failing to cancel my contract for 4 months. Going round in circles with proofs team, finance team, customer service team. Just got hung up on AGAIN? And I’m consistently told to just “go into store” when they’re all closed! Can someone help?

  • k8_st8 Katie staight (@k8_st8) reported

    @ThreeUKSupport Had a text from you saying the problem has been resolved. It hasn't. Data can't be accessed via the hotspot on my phone. The children need to connect their device via the hotspot as they can't do their work on a phone. Your ref: 30341835

  • Graham_B23_ graham (@Graham_B23_) reported

    @ThreeUKSupport I tried the chat gave up after 30mins no response called 333 spoke with someone for 30 mins of try this try that only to be told oh yes there’s an issue in your area? Which is what I told her in the first place!!!!
