Emergency Mobile Alerts are messages about emergencies. They are sent by authorised emergency agencies to capable mobile phones. The alerts keep people safe and are broadcast to all capable phones from targeted cell towers.

The alerts are targeted to areas affected by serious hazards. They will only be sent when there is a serious threat to life, health or property, and, in some cases, for test purposes.

To make sure the system is working well a nationwide test of the Emergency Mobile Alert system is happening between 6-7pm on Sunday 22 May. An alert will be broadcast to all capable phones.
