  • 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.

  • SueRegan73 Suzanne Regan (@SueRegan73) reported from Cardiff, Wales

    @ThreeUKSupport hi my daughter had her new phone today with a new SIM card after and upgrade she activated the sim. But there was nothing when trying to into my 3 for new number would let us log in or update password. Kept saying technical error. Is there a problem.

  • 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

  • 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.

  • 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?

  • 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

  • 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!

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

    Delayed tweets thanks to pants service from @ThreeUK

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

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

  • 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!

  • 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.

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

    @tower_cell @ThreeUKSupport Yes they have. One corner of my village didn't have any signal. There's now low inside signal but at least it's something.

  • 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?

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

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

  • 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 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

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

    Just had the @Huawei E5783B-230 today. I'm setting it up, but I don't see 4G only mode under any network mode settings. Has this been taken away? @ThreeUKSupport @Huawei_Europe

  • 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 🏳️‍🌈 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@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!]

  • eli_woods #TheLifeOfEli (@eli_woods) reported

    @ThreeUKSupport Yes it is a new build, but when we took out the contract for the WiFi they checked this area and told us it would be fine, as we got the contract out just before moving and had problems with it in the old house too which was not a new build

  • RishinPatel03 Rishin Patel (@RishinPatel03) reported

    @CFCJae_ @ThreeUK Apparently there's 3000 tickets available from sporting breaks, around 1800 applications have been made so far and thats incl members as well So I assume for any member it will be down to your luck

  • BomberBrown80 Broon80 (@BomberBrown80) reported

    @ThreeUKSupport hi your reception is terrible in post code fk27xp

  • X3roHero Lorenzo Battilocchi (@X3roHero) reported

    @ThreeUKSupport Then why give users the option to do it from the app... Sounds like a stupid illogical concept. If you put a feature out, it should work. Otherwise, just don't put it in at all..🤦

  • pixiero79 RosieGee (@pixiero79) reported

    @ThreeUKSupport Right, please tell me which options to choose because whatever I choose seems to be the wrong option, people I speak to give me different numbers but they all take me back to the same place! I never wanted the insurance to start with!

  • LewisCanavan Lewis James (@LewisCanavan) reported

    @ThreeUKSupport I can see @EE are replacing all #Huawei mast technology in Hull to comply with new regulations. Are you going to do the same and will this cause a lot of downtime on the network? Thanks..

  • Nbrasso Zathan (@Nbrasso) reported

    @pinecone247 @ThreeUK I would, but 3 only have band 20 and 3 here, and speeds are poor with my pixel 4a 5G

  • glennbowdin Glenn A J Bowdin (@glennbowdin) reported

    @ThreeUKSupport Thank you for your quick reply, we will be in touch, but you have the bank details that you take payment from. Vodafone, BT, EE and others manage it automatically after the final bill, so it is clearly possible. I wonder how many don't notice and never claim the final refund ...

  • EdwardKenton1 Edward Kenton (@EdwardKenton1) reported

    @ThreeUK Dishonest! Changed the number for my mobile broadband without me knowing - then I cancelled “old” number. Over a month later, broadband still not disconnected. That’s because you lied. Horrible company. Untrustworthy as anything. AND STILL STEALING MY MONEY!!!

  • PalmerRomayne Romayne Palmer (@PalmerRomayne) reported

    @ThreeUK shambles of a network provider 😪
