A 'Keep Calm and Carry On' message has been issued by the Government ahead of a new national phone alert text being sent to devices cross the country today (Sunday, April 23).
The Government will send out the alert at 3pm and it will be received by every 4G and 5G device across the United Kingdom.
Officials from the Cabinet Office National Situation Centre said they launched a "major awareness campaign" to ensure the public knew about the test of the system, with new polling on Friday showing 88% of the British public were now aware.
