Latest outage, problems and issue reports in Cardiff and nearby 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

  • 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.

  • 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.

  • 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’vr ever encountered

  • 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

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

    @ThreeUK customer service is horrendous

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

    @ThreeUK I have just had the worst customer service experience I have ever had. My knowledge of your products and services was much better than your staff. Also, TV noise un background made it hard to understand the Glaswegian accent and adviser 2 spoke fast and did not listen 😡

  • 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 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

  • 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 😐

  • 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.

  • 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

  • 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!

  • reece_evans Reece (@reece_evans) reported from Weston-super-Mare, England

    @ThreeUK why am I paying for a service that NEVER works at my house - BS494EQ

  • 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 @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

    On hold to @ThreeUK possibly the worst phone company i’ve ever encountered in my whole life

Latest outage, problems and issue reports in social media:

  • BloggingWasJP Justice of the Peace (@BloggingWasJP) reported

    @ThreeUKSupport Well it wasn’t around 11.30am Monday and several times previously. Are residents objecting to your application to build it extend a mast? And that’s the real reason for the problem

  • ciannegcx Cianne Cass (@ciannegcx) reported

    @AppleSupport @ThreeUK my phone was working fine up until yesterday when @three made me reset my network settings since then my flash for alerts won’t work. It’s very frustrating as I had them in for a reason.

  • harrewis Paul THORNE (@harrewis) reported

    @ThreeUKSupport Absolutely shocking coverage here all week. More like 99% non coverage! Let me with no maps/satnav, no access to car parking apps! Dreadful service! This is in Tenby, not the end of the earth!

  • twitsplatt Steve (@twitsplatt) reported

    @ThreeUKSupport I use the Ring app with cameras. For the last 3 weeks, can't Live View any camera on mobile data with 3. Found out I can get it working if I set my phone to 3G - it doesn't work with 4G/LTE or 5G. Something wrong with your network. Can you help?

  • ArgyleCharlotte Charlotte Argyle (@ArgyleCharlotte) reported

    @ThreeUKSupport - Signal issues in W2? Been down since 2pm-ish

  • AGDun_162 Aldo (@AGDun_162) reported

    @EE And 100% more than @ThreeUK ..who can't even provide a decent 4G Signal

  • lukemotorsport 𝙇𝙪𝙠𝙚 (@lukemotorsport) reported

    @wwodb @ThreeUK You're at Le Mans - comms get battered when cars are out and effectively ringfence anything in the circuit. In 2019 we had a huge issue on le mans esports soundchecks when qually was on. I'd assume itd be similar situation with cell stuff?

  • Scampiuk Chris Williams is typing... (@Scampiuk) reported

    There's only two real reasons for this. 1. A major UK Telco can't implement SSL 2. @ThreeUK want their website traffic unencrypted maybe 3: the site performance is so bad the SSL overhead is one of the 'tweaks' to get around it. I'm struggling to think of any more.. #infosec

  • ChrisMabbatt Chris Mabbatt (@ChrisMabbatt) reported

    @ThreeUK Amazing customer service last Sunday at Three Oxford Street East from Jay, what a gent. Stuck in London, no debit card, no data and no way to access money. Spent time just before closing and sorted for us so we could set up Apple Pay. You have an awesome employee there.

  • Rtclark16 Ryan Clark (@Rtclark16) reported

    @ThreeUKSupport Is there a number I can call tomorrow to speak to someone to check it's not an issue with my individual router?
