  • 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.

  • 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

  • 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.

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

    @ThreeUK customer service is horrendous

  • 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

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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.

  • 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.

  • 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

  • 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.....

  • 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

  • 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.

  • 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..

  • SimoneJonesx Simone Jasmine Jones (@SimoneJonesx) reported from Alway, Wales

    Imagine being a @ThreeUK customer with 2 contracts for years on end and being told to find another service provider because they can’t fix the masts in my area and then refuse to refund what I’ve paid off this mobile or even pay my upfront cost for my next phone 😡 #scabs

  • 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

  • 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

  • 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 😐

  • Sab27 SabrinaS 🌄🌕 (@Sab27) reported

    @ThreeUKSupport i am so sick of having a rubbish signal. This is happening so often yet I'm being charged the full price for my bill everytime this happens. Ridiculous service from #three

  • poshman63 jonathan simson (@poshman63) reported

  • yazjd89 Yaz (@yazjd89) reported

    @ThreeUKSupport hi, we purchased a sim last week and chose today as the day to have our number ported over from a different network but this hasn't happened yet. Is there a certain time of day this happens or should it have happened by now? thanks

  • poshman63 jonathan simson (@poshman63) reported

    @ThreeUKSupport Is there a date to sort out congestion issue? Is this new? Never had a problem before? Is it the upgrade work?

  • redpaperrosecom redpaperrose.com (@redpaperrosecom) reported

    @ThreeUKSupport ... at trying to encourage more upfront information, honesty, and openness as opposed to trying to make customers think there is an issue specific to them / their hardware / their configuration

  • randommuse214 Michelle Ann (@randommuse214) reported

    @ThreeUK recently got internet with you. Very unhappy. Speed is less than 3mbps. We want to cancel and are within 14 days. How do we cancel?

  • Microbedoc2 Jamie Murphy (@Microbedoc2) reported

    I'm sick of @ThreeUK & @NOWTV your 5G & broadband are respectively awful. I feel like data is being delivered by a blind carrier pigeon with one wing. It's really not ok.

  • Coireruadh Coireruadh #FSI 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺 (@Coireruadh) reported

    @ThreeUKSupport I Still experiencing slow speeds in FK21 area. Your Customer Supp said this would be fixed on 5th June. Still no better. Have gone from average 15-20mbps to less than 2mbps! Very disappointed, Contract is up in August will seriously be considering whether to renew
