The government’s new Emergency Alerts system will be tested nationally on Sunday April 23rd.
An emergency alert is a loud, siren-like sound with a message on the screen of your mobile phone or tablet.
The system will enable people to be contacted via their mobile device when lives are in danger. Emergency alerts are sent to compatible mobile devices within an area of risk. They don’t track your location, need your phone number, or collect personal data, and only the emergency services can send them.
You can check an alert is genuine and find out more at gov.uk/alerts
