Why your phone may make strange sounds

A NEW system of “emergency alerts” designed to warn people via their phones or tablets when there is a “danger to life” nearby is expected to launch soon. IN circumstances where there is severe flooding or an explosion, for example, people will receive alerts informing them of the danger and advising them how to stay safe.

The service was initially trialled by the Government during the summer of 2021 as part of a Uk-wide test.

It is set to be launched later this year, as reported by Wales Online.

How emergency alerts

work

In an emergency, mobile phone masts in the surrounding area will broadcast an alert. Every compatible mobile phone or tablet in range of a mast will receive the alert.

The emergency services and the UK government do not need your phone number to send you an alert, you will get alerts based on your current location not where you live or work.

Your personal data will not be collected or shared, your device or your location when you receive an alert, according to the Government.

You will not get alerts if your device is turned off or in aeroplane mode, and the emergency alerts are free. You do not need to sign up for them or download an app and you can opt-out of some emergency alerts, but you are advised to keep them switched on for your own safety.

What happens when you get an emergency alert?

Your phone or tablet may:

Make a loud siren-like sound, even if it’s set on silent

Vibrate

Read out the alert The sound and vibration will last for about 10 seconds and you are advised to stop what you’re doing and follow the instructions in the alert.

Sometimes an alert will include a phone number or a link to the GOV.UK website for more information.
