  • 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.

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

    @ThreeUKSupport Worst company i’vr ever encountered

  • 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

  • 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

  • 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.

  • 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 😐

  • 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

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

    @ThreeUKSupport You have lost me a customer as of today and my complaint is currently with the ombudsman. Your staff and managers are awful!

  • 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.

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

    @ThreeUK customer service is horrendous

  • 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 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..

  • 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.

  • 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

  • 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

  • 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

  • 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.

  • 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

  • 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

  • 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

Latest outage, problems and issue reports in social media:

  • ehroberts1293 Lizzie Roberts (@ehroberts1293) reported

    @ThreeUK I left 3 for another network as they were cheaper. 3 called to offer me a much better deal. Explained I’d already left, they said that’s fine they will still honour the deal for me. Cancelled with other network to come back to 3 and now you’re saying you won’t honour it.

  • Arkam_95 Arkam (@Arkam_95) reported

    @ThreeUKSupport It doesn't work because it keeps asking for the authentication code sent to the number.

  • polnyypesets Citoyen brexilé 🇪🇺🇬🇧🇫🇷🏴󠁧󠁢󠁷󠁬󠁳󠁿🇸🇪 (@polnyypesets) reported

    OK @ThreeUK you are maintaining your record of appalling customer service. I want to reset my web password. The link does not send an email as promised. Your “support” chat wants me to provide information THAT I CANNOT REMEMBER to “verify” me before they will help me. Absurd.

  • silentscreams_9 Bearded Zombie #standwithukraine ☮️🌱🇺🇦♠️ (@silentscreams_9) reported

    @ever_longing @OfficialRandL @ThreeUK Ticketmaster are still not refunding. It's awful PR refusing to refund. None of these people are likely to risk buying a ticket again.

  • Arkam_95 Arkam (@Arkam_95) reported

    @ThreeUK hi, I ordered a replacement sim last Wednesday but yet haven't received yet. Please help?

  • LGKflux O L U W A B U C H I (@LGKflux) reported

    @ThreeUKSupport @ThreeUK is a ****** network service

  • yeslads67 yeslads67 (@yeslads67) reported

    @ThreeUKSupport help pay my bill. You won’t accept my card and your live chat won’t work

  • iSax_UK Alistair Parnell (@iSax_UK) reported

    @ThreeUK I’m trying to work out why I’ve just spent an hour on chat being told I’m a ‘valued’ customer only to be offered a worse SIM deal than I could have got directly on your website myself. This feels incredibly dishonest! Has anyone else had this experience?

  • TheSoapboxGuy Chris Graham (@TheSoapboxGuy) reported

    @ThreeUKSupport 4) DPD said the parcel needs to be collected by this Saturday. So now no phone and nobody really seems to know what is going on. I still want the phone & new contract but with no solution I will end up having to go elsewhere

  • spinningoutaday Mr Danny (@spinningoutaday) reported

    @ThreeUKSupport It's been around 4 or 5 weeks roughly. Biggest issue is the phone still shows good signal, so WiFi call doesn't always kick in and then the other end can't hear me on calls. My partner has contacted I think, I'm with iD Mobile who are investigating for me.
