Select UK residents are set to receive further alarms and warning messages to their mobile devices today, as the Government carries out a second test of its new Emergency Alerts System.
However, not everyone is set to receive the alert.
It comes after the Conservative Government rolled out the initial test for the system on Sunday (April 23), with every mobile phone in the UK supposed to be pinged by the loud siren and accompanying message. But the alert showed up prematurely for many, while others didn't receive the message until hours after it was scheduled.
