This second test of the national emergency alert system, and first since 2023, will be on Sunday, September 7, at 3pm.
Mobile phones connected to 4G and 5G networks will vibrate and emit a siren sound for up to 10 seconds, with users being told that it is a drill.
The Government has used the system to issue real warnings five times, including in January during Storm Eowyn to warn people in Scotland and Northern Ireland about severe weather.
Approximately 3.5 million people across Wales and south-west England received an alert during Storm Darragh last December.

A 500kg unexploded Second World War bomb found in a Plymouth back garden triggered a warning to some 50,000 phones in February last year.
Messages can be targeted to relatively small areas to pinpoint those at risk.
Some 15,000 phones were alerted during flooding in Cumbria in May 2024, and 10,000 received a warning during flooding in Leicestershire in January this year.
The system is designed for use during the most likely emergencies to affect the UK and warnings would also be transmitted on television, radio and locally by knocking on doors.
Pat McFadden, Chancellor of the Duchy of Lancaster, said: "On Sunday September 7, we will hold a UK-wide test of the Emergency Alerts system to ensure it works when we need it most.
"It is a vital tool for keeping the nation safe when lives are on the line – and every minute matters.
"During Storm Darragh and Storm Eowyn, as millions faced dangerous extreme weather, I saw first-hand how effective it was at getting life-saving advice to at-risk communities in an instant.
"We do not use the system often, but like the fire alarm in your home, it is always on standby should we need to act."
