Mobile phone devices across the country will sound a siren in a matter of days as the Government's new emergency alert system is tested.
The Government has recently released new details about the test, which will take place this weekend, explaining the wording of the upcoming emergency message. The siren will sound and vibrate on devices across the country in a nationwide test, with the UK Government aiming to use the system to warn of life-threatening incidents in both local and country-wide situations in the future.
The "Armageddon alert" will require millions across the country to acknowledge the test before carrying on as normal on devices. But when will the alert sound, what will it sound like and can you opt out?
