    I need to switch mobile phone providers! Apparently if your a @ThreeUK customer like me and armageddon arrives, we’re the last to know and on our own cause everyone else got a head start 😝 Should have realised how bad they were when they sponsored Chelsea #EmergencyAlert

  • igj777almeria Ismael Gonzalez (@igj777almeria) reported

    @welshfrench @TeresaC123 @ThreeUK I haven’t received it on 4G Three (my personal phone) neither 4G EE (work phone) Both are on iPhone with iOS above 16.1 If it were a real emergency I would have died around 10 hours ago They must include every phone on 3G and phones who are on areas not covered by their providers

  • MikeBfpo Mike Wild (@MikeBfpo) reported

    @ThreeUK I would post the screenshot of my message, but it never arrived!

  • CSI_Pete Pete Wright (@CSI_Pete) reported

    @robininohiousa @ThreeUK Three doesn’t use 2G. Hence their name. They started as a 3G service only (using Orange or Voda to provide 2g infill until they’d built enough of their own masts!)

  • Gaz_247_Wishart Gary Wishart⚫⚪ (@Gaz_247_Wishart) reported

    @ThreeUK hi ... any reason why your network didn't work with the emergency signal yesterday??

  • nickgrayo Nick Gray (@nickgrayo) reported

    @ThreeUK Utterly useless network

  • Clarelwhyte Clare Riley (@Clarelwhyte) reported

    @ThreeUK Think every customer on three should be able to stop their contract immediately without penalty due to this massive fail!

  • DTobasco Don Tobasco (@DTobasco) reported
