On Sunday 7th September at 3pm, the UK government will test the Emergency Alerts system.

The test will be sent to all compatible 4G and 5G mobile phones and tablets across the UK. You will hear a loud siren-like sound, your phone will vibrate, and a message will appear on the screen confirming that this is a test. The sound and vibration will last for about 10 seconds. You will not need to take any further action.

WHAT IF I NEED TO TURN THE ALERT OFF?

The Emergency Alerts system is an important tool for reaching the public in emergency situations. However, if you need to turn off these alerts (including the test), visit https://www.gov.uk/alerts/opting-out for step-by-step instructions.
