Thousands of Brits have been left baffled as their phones failed to sound and receive the Government's new emergency alert trial on Sunday.
While many people reported their phone sounding the alert at around 3pm today (April 23), many others were confused when their mobile remained silent. The new system, which is similar to ones already in place in the US, Canada, The Netherlands and Japan, has been put into place by government officials so they can contact residents in the case of a life-threatening emergency.
Phones are supposed to let out a siren like sound, vibrate and show a message that reads: "For weeks UK residents have been warned about the alarm that was set to go off on every phone. In a real emergency, follow the instructions in the alert to keep yourself and others safe. Visit gov.uk/alerts for more information. This is a test. You do not need to take any action."
