The Wireless Emergency Alert (WEA) is a system that broadcasts public safety messages (like AMBER Alerts, Earthquake Early Warning Alerts, Tsunami Alerts) over the commercial cellular system. Customers with compatible mobile phones can receive geographically targeted, text-like messages alerting them to threats to safety in their area. All WEA alerts, regardless of type, behave the same. The device makes a distinctive notification sound and vibration, and the message pops up in a text window on the screen.
