People in Milton Keynes may receive an emergency alert on their mobile phones as part of a Government-run test today (22/6).
Between 1pm and 2pm, some mobile phone networks will be trialling the alert ahead of the Government's summertime launch of the new emergency alert system.
If you have an Android device, there is a small chance that when you get a test alert your device may make a loud siren-like sound.
A Government spokesperson explains: "Your phone or tablet may make a loud siren-like sound, even if it’s set on silent, vibrate and read out the alert.
"The sound and vibration will last for about 10 seconds.
"Stop what you’re doing and follow the instructions in the alert."
The test alert itself 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."

The alert system will be used in a number of scenarios such as during crises like serious flooding or fires.
Those who wish to opt-out of the system should be aware that only some alerts can be disabled, as the most important ones will still be received.
