Today (Sunday), the government is set to send an emergency alert out to mobile devices up and down the country. The nationwide test will say how it plans to keep families informed in the event of an actual real-life emergency, such as severe flooding, extreme weather, or fires.
A siren is set to sound and devices will vibrate once the government hits send. Your device may even read out the alert, which is set to last a maximum of 10 seconds.
Since the alert was announced, people have been split by its usefulness, with some politicians leading the charge to encourage phone users to turn them off. Fact-checkers say there has also been misinformation spread about the alert.
