SOME mobile phone networks in the UK will be testing emergency alerts between 1pm and 2pm today (June 22)

If you have an Android device, there’s a small chance you may get a test alert.

The phone might also make a loud siren-like sound.

The alert will say: "This is a mobile network operator test of the Emergency Alerts service. You do not need to take any action. To find out more, search for gov.uk/alerts."

Why is it happening?

Emergency alerts are used as a vital tool to help people respond to emergencies or threats on a national or local level.

The system enables the government to more quickly and effectively send warnings to people across the country, allowing them to get to safety in the event of a threat.

The alerts that will be sent to some phone users on Tuesday are part of a test only and do not require any action to be taken.
