Phones across the country play siren and vibrate in latest test of service for use during emergencies
Millions of phones across the UK played a siren and vibrated on Sunday afternoon as the government carried out a nationwide test of its emergency alert system.
The alarm, which sounded at 3pm, lasted for 10 seconds and was accompanied by a message on screen making clear it was only a test.
“This is a test of Emergency Alerts, a UK government service that will warn you if there’s a life-threatening emergency nearby,” the message read. “You do not need to take any action. In a real emergency, follow the instructions in the alert to keep yourself and others safe.
