Emergency Alerts is a UK government service that will warn you if there’s a danger to life nearby. In an emergency, your mobile phone or tablet will receive an alert with advice about how to stay safe.
Your mobile phone or tablet may:
make a loud siren-like sound, even if it’s set on silent
vibrate
read out the alert
The sound and vibration will last for about 10 seconds. An alert will include a phone number or a link to the GOV.UK website for more information.
There are instructions on how to opt out of Emergency Alerts at this LINK, for e.g. victims of domestic abuse who have a concealed phone hidden from their abuser.
Further information on Emergency Alerts is at: https://www.gov.uk/alerts
