Mobile phones across the UK will get a loud alert this month as the government introduces a new system for emergencies in 2023.

A time and date has officially been set for this month where around 90% of mobile phones and tablets across the UK will sound an alarm as part of the government's new emergency alert system.

The government has said it could be "the sound that saves your life" as they prepare to roll it out in 2023 following recent pilot tests in the Reading and East Suffolk areas. US, Canada and Japan have similar services.

The alert will see messages pop up on millions of phones and tablets, along with a sound and vibration. You will have to tap 'OK' or swipe it away to continue using your phone.
