The Fort Worth Press - Don't panic: UK phones to sound at once in emergency drill

The nationwide test comes as officials seek to strengthen the country's resilience amid more frequent extreme weather events and concerns around Russia's war in Ukraine.

At 3:00 pm (1400 GMT), most of Britain's 87 million mobile phones and tablets will emit the noise and vibrate for about 10 seconds, the government has said.

Users will also receive a message saying the warning is only a drill, in what is just the second test of the national emergency alert system following the first in 2003.

"Just like the smoke alarm in your house, the fire alarm in this building, it's important to test these things now and again," Pat McFadden, the minister responsible for the system, told BBC radio on Thursday.

The government has in recent weeks embarked on a publicity drive to minimise any shock caused, including through announcements at rail stations and signs on motorways.

It picked the date and time to try to minimise disruption -- for example there are no top-flight men's football matches this weekend due to a round of international fixtures.

It has no control over events like weddings, funerals, or children's birthday parties, however.

"There's no perfect time to do these things," conceded McFadden, adding: "There will be something that is disturbed as a result of this."

The government has used the system to issue real warnings to local areas five times in the past two years.

In January, some 4.5 million people in Scotland and Northern Ireland received an alert during Storm Eowyn after a red weather warning was issued, meaning there was a risk to life.

A 500-kilogram (1,100-pound) unexploded Second World War bomb found in a back garden in southwest England triggered a warning to some 50,000 phones in February last year.

The system is designed for use during the most likely emergencies to affect Britain where there is the possibility of a loss of life.

Warnings would also be transmitted on television, radio and where appropriate by knocking on doors.

Similar alerts are issued in the United States and Japan.

Only devices connected to 4G or 5G networks will get Sunday's alert.

It comes after the government published a "Resilience Action Plan" in July which cited the upheaval of the coronavirus pandemic, US President Donald Trump's tariffs and cyber attacks.

In the foreword, McFadden also mentioned "war on the continent of Europe that catalysed the largest rearmament of European powers since World War II".

"The whole of the UK's national resilience -- our economy, defences and biosecurity -- is being tested like never before," he wrote.
