  • 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.

  • 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.

  • 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!!

  • 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

  • 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!! 👎👎👎

  • 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.

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

    @ThreeUK network down after I ios update overnight #threedown

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

    @omnitix @ThreeUK first 3G only network innit

  • 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

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

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

  • pringoli lynda pring (@pringoli) reported from St. Julians, Wales

    @ThreeUK hope network is working correctly now! Hit and miss since yesterday 🤔

  • 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.

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

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

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

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

  • 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.

  • Moe3k9 C-Note (@Moe3k9) reported from Cardiff, Wales

    @ThreeUK fix up

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

    @ThreeUKSupport network issues in Cardiff..

  • 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.

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

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

  • 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 😡

Latest outage, problems and issue reports in social media:

  • LauraSavvas Laura Savvas (@LauraSavvas) reported

    @ThreeUKSupport I requested a PAC code when I was due a free upgrade and paid a bill on 24th May. I cannot login to my online account to check I owe you anything but I was wary to give card details over the phone.

  • P_HEDGEHOG Alex Leigh (@P_HEDGEHOG) reported

    @DVLAgovuk still not answering their phone OR chat. A week ago they told me to 'DM' them on Twitter so they could help. If anyone needs to research a black hole, let me direct you to their DMs ;) Also @ThreeUK @Three_Is_Broken is mostly dead. I mean HOW HARD IS IT! #head #desk

  • Anthonymannion3 Anthony mannion (@Anthonymannion3) reported

    @ThreeUKSupport My postcode is ub9 6ha only problem is this isn't isolated to just this postcode a40 Westfield is w12 7gf and then there's junction 26 on the m25. Everytime I drive past these points the signal on my phone will show full but the call will go silent.

  • Sectimus Amelia Magee (@Sectimus) reported

    @ThreeUKSupport @griptapebeercan Hey Three, would this be supported on wearable devices that support eSIM like the Samsung Galaxy Watch 3 4G? And would I need to purchase a seperate plan for it?

  • Anthonymannion3 Anthony mannion (@Anthonymannion3) reported

    @ThreeUKSupport Hmmm we'll see I guess my contract is up in a few months you have till then. Never really had these issues with EE strangely.

  • sergeiscout Brian Robinson (@sergeiscout) reported

    Come on @ThreeUKSupport yet again the three signal is not available in my area. If you were upgrading to 5G that would be good. But not on the plans. Refunds must be due!

  • BoydyR Boydy (@BoydyR) reported

    @ThreeUKSupport G21 3AF, it isn't isolated to this area, coverage check by 3 app says all is good, but it's absolute terrible, restarted phone twice now

  • Simon8084 Simon K (@Simon8084) reported

    @ThreeUK Someone has taken out a contract in my wife’s name at a different address. We’re shocked this could happen so easily! Please can you contact us immediately to close down this fraudulent activity. We called ur help no. but it seems they will get back in 7 days!

  • SaraCurlyWurly Curly 🇬🇧 (@SaraCurlyWurly) reported

    @ThreeUKSupport Yes that's correct it's HP21 area, I've got the Huawei app now, but it's not showing any problems, I've turned it off and on, I've turned my phone off and on, it's been very up and down starting last week, but today it keeps saying I'm disconnected when I'm not!

  • Luke41010101 Luke⭐⭐ (@Luke41010101) reported
