Emergency Alerts are a public information service that the UK government has developed to alert people about emergencies, both nation-wide and in their local area.

The technology used allows a text-based message to be broadcast to a specific area, meaning any device in or entering that area immediately receives the message.

The message will detail the emergency and actions people need to take to ensure their safety.

Their purpose is to help save lives in emergency situations by issuing a warning and clear instructions about how best to respond.

Emergency Alerts appear on your device's home screen. You must acknowledge them before you can use your phone’s other features.

The alerts appear as a text-message notification and will include telephone numbers or website links containing further information.

A loud, siren-like sound and vibration will accompany the message to raise awareness of the hazard or threat.

Read the content carefully. An Emergency Alert is likely to include a link to gov.uk/alerts where further information is contained, and/or a helpline.

Alerts are sent to warn you when lives are in danger and, sometimes, for test purposes.

Take the appropriate action as directed by the message, and consider alerting others in the area who may not have received or seen the message.

Emergency Alerts should be received on a majority of devices. However, there are some factors which might mean you will not receive an alert. These include:

• Where a device connects to 3G or a 2G signal. This can often happen inside buildings. A device needs to be on 4G or 5G to receive the alert.
• The device does not have the latest software update or the software update has not been released (older devices have a slower update cycle).
• The device is not able to receive the alerts as it is no longer supported.
• The device is not a 4G-enabled device.
• The device was switched off.
• The device was not connected to a mast broadcasting the Emergency Alert.

Yes, if it does not have the latest software. Most newer phones (from 2015 onwards) can receive the messages if they have the latest software update.

Phones over six years old are likely to require some changes to the settings by the user.

Older models of Apple (before iPhone 6S) that do not support iOS 14 and older models of Android (generally older than Android 9 / Pie) will not be able to receive Emergency Alerts.
