All UK cell users to get emergency alert system

A siren-like alert will be sent to mobile phone users across the UK next month to test a new public warning system over life-threatening events such as severe weather events, the British government announced on Sunday.A UK-wide alerts test will take place in the early evening of Sunday, April 23, which will see people receive a test message on their mobile phones. The government said the new Emergency Alerts will be used very rarely, only being sent where there is an immediate risk to people’s lives, so people may not receive an alert for months, or even years.
