    yet again @ThreeUK @ThreeUKSupport proving that their internet isn't fit for service - in the last few hours, it disconnects every few minutes and only reconnects when i get up to manually reset it. don't suggest talking to your support team, none of that helped. i am switching.

  • chloemcclean Chloe McClean (@chloemcclean) reported

    @ThreeUK I have recently relocated to London (SW2 3AA) so disappointed my signal is shockingly bad in my new house to the point of no signal. I would expect the capital city of the UK to have basic good service. Can you please explain? My dad has over 6+ contracts and is unhappy!

    @ThreeUKSupport How does taking the sim out of my WiFi hub and putting it in a phone going to help me use my devices?

  • CFC_Jac Jack 👑🇦🇺 (@CFC_Jac) reported

    @CFCMod_ @ThreeUK Bro wtf 😳

  • Eddiee_91 Eddie Wolfreys (@Eddiee_91) reported

    @ThreeUKSupport Still the same issue I’m afraid. Tried on chrome on my laptop, chrome on my mobile, safari on my mobile… same error as I reset the password

  • Bawlk_3 Blake 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@Bawlk_3) reported

    @ThreeUKSupport your service has been terrible over the last few days all the way down the east coast of Scotland from Aberdeen down via Stonehaven, Arbroath, Dundee, St Andrews, Leaven etc. It's not just my phone, my partner and our mobile MiFi.

  • MarinerMart87 martin lusty (@MarinerMart87) reported

    The @ThreeUK signal is absolutely disgusting. What a joke. 8/9 years as a customer ... DN31 area.... shocking 😤 😤😤

  • ChrisstylesWeb Chris Styles (@ChrisstylesWeb) reported

    @ThreeUKSupport @ThreeUK can someone please DM me. I had a bizarre issue with a new sim and the chat support got disconnected. Despite that the guy investigated on his own and fixed my issue, making sure everything was ok and working. I want to make sure he is recognised. Thx

  • GarethJBond Gareth J Bond (@GarethJBond) reported

    @ThreeUKSupport Thanks for rep,y Scott. Signal has always been like this had text message a few months back saying it was being improved but no better. Media chat says RWY later.
