    @ThreeUKSupport The data signal is almost non existent here (Chapelfields NR2). Thank goodness I have EE on another phone, allowing me to tweet.

  • ethandavidlee Ethan Lee (@ethandavidlee) reported

    @ThreeUKSupport You guys have randomly paid me £26? Not complaining about money but I don’t think this was meant for me, I haven’t been a customer for years.

  • PeskyBob Rachel Bobeckyj (@PeskyBob) reported

    Hey @ThreeUK any idea of when you'll fix the mast in Lyme Regis, Dorset? It must have been down a week now! It came back for a few hours the other day... When I got about 20 texts comes through in about 20mins. No idea if I've gotten any replies since then! Pretty plz fix it ASAP

  • cheamarena Andrea (@cheamarena) reported

    Worst network coverage ever @ThreeUK, so bad I couldn’t even send this tweet.

  • chrisjenko Chris Jenkins (@chrisjenko) reported

    @tom_w_harvey @Scouting4Girls @ThreeUK Really bad in central london. Keeps telling me I have 4G but actually have no connection at all. I feel like this is a new development

  • PebHeed PebHeed (@PebHeed) reported

    @MoneySavingExp 1 terabyte for £1 a month wouldn’t tempt me back to @ThreeUK When you can’t get a signal in a major city, avoid, no matter how cheap it is. Worst network I’ve used in years. Paid to leave early. It was worth every penny to escape.

  • ShaVerZ_ ShaVerZ™ ツ (@ShaVerZ_) reported

    @ThreeUKSupport @ThreeUK Absolutely useless, worse than your overseas call centres! I had to explain over and over despite clearly describing my issue (again)! Shocking that you don't know how your own network works!

  • ross_observer The Observer (@ross_observer) reported

    My mums been without signal for 2 months thanks to @giffgaff, we’ve changed her over to @ThreeUK and she’s back up and running and for cheaper! Giffgaff have the worst customer service by any company I’ve ever experienced. Good riddance.

  • rab1dkorndogg andy marsh (@rab1dkorndogg) reported

    @ThreeUK It's still on? I was hoping it'd be cancelled by now, their acting is awful 👍

  • OllyBowman Olly Bowman Photo (@OllyBowman) reported
