  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @JohnDubyaUK @ThreeUK Yeah they’re all in such a rush to get 5G out, they just seem to have given up on trying to get 4G sorted out. At least show me I’ve got a crap signal, don’t pretend it’s all full speed and awesome.

  • oxWelshElisexox 🏴󠁧󠁢󠁷󠁬󠁳󠁿Welsh Elise🏴󠁧󠁢󠁷󠁬󠁳󠁿2k (@oxWelshElisexox) reported from Cardiff, Wales

    @EnglishPhoebeX1 @ThreeUK @ThreeUKSupport **** mines been cutting out on calls but not no network

  • Mrs_Thomas82 Sarah Thomas 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Mrs_Thomas82) reported from Maesycwmmer, Wales

    @ThreeUK My service has been fine. My husbands on the other hand has been non-existent since last night.

  • 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.

  • alunT Alun Thomas (@alunT) reported from Caerphilly, Wales

    @ThreeUK network down after I ios update overnight #threedown

  • MartynPreece79 Martyn Preece (@MartynPreece79) reported from Cardiff, Wales

    @ThreeUK great if you have no issues, as soon as there’s a problem they give all the bull!! 👎👎👎

  • MK__C MK (@MK__C) reported from Barry, Wales

    Imagine waiting 30 odd minutes for the upgrades department to then be put to customer service who then says yeah upgrades is down at the moment @ThreeUK 🙃 Legit wasted my time

  • stumpy_juk Matthew Jones (@stumpy_juk) reported from Cardiff, Wales

    @ThreeUKSupport network issues in Cardiff..

  • 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

  • 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 Been through this, you won’t check as it’s a business account and the business team never follow up. 2 years ago Caerphilly had around 40mb down now it’s about 4mb down and no one there seems bothered.

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

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

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport This was in CF83 1XP and it’s been terribly slow for months now.

  • KrisheleG Krishele Guzman (@KrisheleG) reported from Cardiff, Wales

    Horrible T&Cs usage by @ThreeUK and #Wuntu on their Google Play offer. Tricked me into charging my bill instead of using the offer!!

  • TicketTattle Andrew Thomas (@TicketTattle) reported from Cardiff, Wales

    @omnitix @ThreeUK first 3G only network innit

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

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • KrisheleG Krishele Guzman (@KrisheleG) reported from Cardiff, Wales

    @dlever21 @ThreeUK My problem was they added a new condition this time that said if you haven't used it since January. but @ThreeUK ran the offer in May and I used it then. Guaranteed they caught LOADS of people out 😡

  • 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.

  • welsh_stu 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Stuart 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@welsh_stu) reported from Caerphilly, Wales

    @ThreeUKSupport They said wait a week and try again, and it’s still horrendously slow.

  • Just_a_Coolbean 𝕂ayleigh (@Just_a_Coolbean) reported

    @ThreeUKSupport Just phone contract and no issues with fraud recently x

  • londonvino Natasha Hughes MW (@londonvino) reported

    Totally rubbish service from @ThreeUKSupport I have roaming on my plan, my phone is enabled. Can I get a 4G (or even a 3G) connection in Spain? Can I hell. Their office hours are when I’m out on visits, so can’t contact them as I have no Wi-Fi access during those times #epicfail

  • cinzywincy Dr Chin Shady 🇮🇲🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@cinzywincy) reported

    @ThreeUKSupport This isn't an accessibility issue - your live chat are just lying and replying with platitudes and refusing to answer questions. How hard can it be to reinstate someone's account that you suspended in a major error?

  • miss_cattybee Catherine Black 💘 (@miss_cattybee) reported

    @ThreeUK the signal in Newry is terrible. Are there any plans to rectify this?

  • NeilPyper Neil Pyper (@NeilPyper) reported

    @ThreeUKSupport Surely a lot of people wanting to use your network in central London is something you could predict and plan for? Along with your lies about inclusive EU roaming, this makes me minded to go elsewhere when my contract ends.

  • scottedwerd Scott price (@scottedwerd) reported

    @ThreeUK hi three, I have been a loyal customer for many years and I have been having problems contacting three about my billing and payments and have had problems with the automated system taking payments which has lead me to be cut off ? Can you help

  • MotherwellCEO Motherwell CEO. Kateblakemore.com (@MotherwellCEO) reported

    Couple of hours water trying to sort issues with yet again @BarclaysUKHelp & @ThreeUK completely shocking customer services.

  • cinzywincy Dr Chin Shady 🇮🇲🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@cinzywincy) reported

    @ThreeUKSupport Oh, its with the security team, they have no idea when it will be done but asking the chat team won't help apparently. So everything I was told yesterday was rubbish. And they tried to close the chat. This is atrocious.

  • Tipsy82479999 Tipsy (@Tipsy82479999) reported

    @ThreeUKSupport Please check a signal in City Centre at York? I am having a difficult recently. Most of the time internet too slow or lost in city centre, please...

  • nicolajayranson Nikki Ranson (@nicolajayranson) reported

    Never thought I would see the day that I say I can’t wait to be on @VodafoneUK ….. currently in Edinburgh for the day and Vodafone is 5G on the husbands phone and I’ve only 3G on @ThreeUK … Hurry Mr Postie and deliver my @VOXI_UK sim!!!
