The government is trialling a new emergency alert system today (April 23) which will see all UK phones being sent a warning message accompanied by a siren sound and vibrations.
At 3pm, the emergency test alert will be sent out, which will appear as a message on your smartphone. It'll last for around 10 seconds and you won't need to take any action.
The system has been designed in order to warn people of dangers such as flooding or extreme weather, but it has faced criticism from the likes of domestic abuse charities, who fear the alert will make others aware of victims' hidden phones.
