UK wide Emergency Alerts test - 3pm Sunday 23 April 2023

Emergency Alerts is a UK government service that will warn you if there’s a danger to life nearby.

In an emergency, your mobile phone or tablet will receive an alert with advice about how to stay safe.

What to expect

Your mobile 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

This video shows you what the alert will look and sound like.

If you're driving - don't pick up your mobile

Using phones while driving is dangerous and illegal. Don't pick up your phone or try to read the message.

Remember this is a test. It will only last around 10 seconds after which it will switch off automatically

What you'll see on our network

We'll be using our electronic signs to remind people not to use phones while driving. Here's what you can expect to see.
