    @ThreeUKSupport I travel for work, completely lost my network coverage on the outskirts of Blackpool yesterday, at home 21 hours later, a network reset and I still haven’t got it back. Your coverage checker isn’t reporting any issues and doesn’t seem to give me the option to.

  • Kennethjay Kenneth (@Kennethjay) reported

    @EITMonline and I thought @ThreeUK was bad.

  • richvdh Richard van der Hoff (@richvdh) reported

    @ThreeUKSupport Thanks for being absolutely zero help, @ThreeUK. For the record, I eventually managed to speak to someone via the "your handset has been damaged" option (4,3,5). Unimpressive.

    Thank you @ThreeUK @ThreeUKSupport @SalesforceUK for the four emails and text message to say my Three Business bill is ready. Thank you also for being unable to log in on my phone to your useless customer portal to see it! Utter incompetence.

    @ThreeUKSupport Mark and Holly, thank you for taking the time to answer my questions. It was very helpful. One last thing. If I use this Sim and suddenly go to a Go Roam compatible country without going to UK and registering, no problem, right?
