At 3pm on Sunday 7th September, there will be a nationwide test of the emergency alert system to mobile phones.
The alerts are designed for situations where there is an imminent danger to life, such as during extreme weather events or a terror attack.
Compatible phones - the vast majority of those currently in use - will vibrate and make a siren sound for roughly 10 seconds.
If you care for a vulnerable person, who may be upset by the alert, or may not understand, please do try to reassure them that this is just a test, and not a real emergency situation.
Whilst it is advised to keep these alerts on your mobile phone, you can opt out of receiving them - please read the article below for more information.
The UK's emergency alert system will be tested for the second time on Sunday 7 September.
