  • thisisjmx J∆MES VINCEΠT 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @PedroClarke1 @ThreeUK While theres different types of mast designs. don't see problem with monopoles especially new designs. people demand better connectivity but reuse the infrastructure in their area. As long as an Operator is sensible on planning Meeting there's no reason to decline a request

  • CatTPeters Cat Peters (@CatTPeters) reported from Penarth, Wales

    @fonehouse hi there, I’ve just upgraded my phone, I’m still on @ThreeUK and it says “Sim not supported”. Please can you help?

  • cymboi MH 🏴󠁧󠁢󠁷󠁬󠁳󠁿🏳️‍🌈🇪🇺 #yescymru (@cymboi) reported from St. Julians, Wales

    @ThreeUK How come you are charging for the Go Roam? It was always apart of the package. Makes me think that your packages are no better than any other network and such poor signals. Will probably leave Three because of this.

  • paullittle1977 Paul Little (@paullittle1977) reported from Newport, Wales

    @ThreeUKSupport please could you confirm when the mast work is likely to be completed in the np20 5 area of Newport, your network checker states repairs have been taking place for a week and I have had very little or no coverage for the last week. Thanks

  • thisisjmx J∆MES VINCEΠT 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @ThreeUK do you have existing customer offers on the 5G cube?

  • claracluk claire wheatley (@claracluk) reported from Barry, Wales

    @ThreeUK network coverage lately is awful. I may need to consider moving after 18 years

  • LisardoVivas Lisardo Vivas (@LisardoVivas) reported from Cardiff, Wales

    @ThreeUKSupport Well that’s the problem, I didn’t requested my wife had the same message and she didn’t request it either.

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

    Delayed tweets thanks to pants service from @ThreeUK

  • thisisjmx J∆MES VINCEΠT 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    Does the @Huawei B535 support VoLTE? Your site says no. But with the AI Cube B900 supporting it, it wouldn't make sense for this new model not to. @ThreeUKSupport

  • Gezitsme Geraint Herbert (@Gezitsme) reported from Cathays, Wales

    @ThreeUKSupport hi. I’ve been with you and few months and i’m really struggling with signal when indoors. Today I had two bars of 5G and couldn’t load anything. Later went to full bar 4G and same issue. Have videos to show if helpful.

  • thisisjmx J∆MES VINCEΠT 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @ThreeUKSupport I took a look on the Hi-Link app. Seems like @Huawei removed it. That's really bad of them to do that

  • djleekee Lee Smith 🌻 (@djleekee) reported from Cardiff, Wales

    Hi @VodafoneUK ever since @ThreeUK put a new 5g mast up less than 100m from my house I have barely had any signal in my house and surrounding area. Please can you investigate postcode cf11 6dr Thank you.

  • CPMumma79 Js Mum (@CPMumma79) reported from Cardiff, Wales

    @ThreeUK be aware i just got charged £15 for a 21 minute conversation with another mobile user! That is appalling. Please explain why your charges have gone up 250% I will be changing network ASAP.

  • thisisjmx J∆MES 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @ThreeUKSupport Well I don't check it very often but around this time when I want to see my bills & usage it only works properly some times. No I've not talked to any other team. I've cleared cache thought that might help. [Apparently you've got a new system that is due to launch at some point!]

  • thisisjmx J∆MES VINCEΠT 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @PeterClaydon @PedroClarke1 @ThreeUK I wouldn't say clutter. It's the technologies needed. There really isn't anything wrong with that. I would like to see more of the cabinets green, especially to help blend more with hedges that might be behind.

  • thisisjmx J∆MES 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    Excuse me for being blunt here @ThreeUKSupport but what is with your trash My3 app? Can't load recent usage, [pdf bill ain't ready yet but that's fine, today is reset day] Website won't give me usage. Why is this a regular basis oops we have an issue thing?

  • kellsandbulls 𝕂𝕖𝕝𝕝𝕪 (@kellsandbulls) reported from Victoria, Wales

    @ThreeUK is there a problem with the services I am not able ring out it is saying this is an important announcement you can no longer ring 153 from my handset use 118333 I need to use my phone!

  • cymboi MH 🏴󠁧󠁢󠁷󠁬󠁳󠁿🏳️‍🌈🇪🇺 #yescymru (@cymboi) reported from Victoria, Wales

    @ThreeUK what a load of rubbish customer service is!!

  • thisisjmx J∆MES 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@thisisjmx) reported from Dinas Powys, Wales

    @JimObasa1955 @ThreeUK People like this is the reason we need to put stupid instructions on packaging!

3 (Three) Issues Reports

Latest outage, problems and issue reports in social media:

  • kentnicklloyd Nick Lloyd (@kentnicklloyd) reported

    @ThreeUK Perhaps it might be because you don't appear to know how to run a phone network, just about every other ”major network" will give an eSIM to an existing customer without a problem, 3 says no you can't have one, I don't understand why 3 are stuck in the 20th century so much🫣

  • NinaJaneGunner Nina (@NinaJaneGunner) reported

    @Fern_Britton @carr1e73 @ThreeUK That includes those that use the 3 network for example I and my family are with ID Mobile who use 3’s network and we didn’t get the alert either

  • CozMicCozza Corry Littlefair (@CozMicCozza) reported

    @ThreeUK So you put my SIM plan up a crazy amount of 15%, then fail to send the government "Alerts"! I want a service provider, that provides a service - let me leave my crap contact, that has poor signal please!!

  • robwww Rob (@robwww) reported

    @Dr_Jon @ThreeUK The Vodafone merger will help, give it a few months...

  • SafinaKhann Safina Khan (@SafinaKhann) reported

    The emergency alert didn’t go out to the people (like me ) with the provider three @ThreeUK 🫥 #emergencyalert

  • Dr_Jon John Michael Leslie (@Dr_Jon) reported

    I forgot about the Emergency Alert this afternoon... luckily being on @ThreeUK they didn't give me a shock but let me enjoy my afternoon in peace... Bit of a worry if a #ZombieApocalypse happens tho...

  • ZoeSomebody Zoe Somebody (@ZoeSomebody) reported

    I've had enough of 3, rubbish coverage, can barely have a conversation with people. Then today they couldn't even send me an effin emergency alert. And I pay for this #ThreeUK #EmergencyAlert

  • AndyPBurton Andy B CP1905 🦅⚽️🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧🇺🇦🔴💙🦅🟢⚪️ (@AndyPBurton) reported

    @SteveRiches4 @ThreeUK Exactly the reason that today was a TEST, so any issues could be resolved.

  • polbikers Kevin 🌍🏳️‍🌈🏳️‍⚧️ #ToriesOut #NoLGBWithoutTheT (@polbikers) reported

    @sarumbear @ThreeUK It’s their project. They should have had a project manager looking after it. I agree the companies that failed share responsibility for the technical fail. Bearing in mind other countries have had similar messaging for over a decade it’s a farce!

  • MairaLaumete Maira Laumete (@MairaLaumete) reported

    @beccytad @ThreeUK Same here, no emergency alert in our house, kinda feel like we have missed out. We are with Three.
