Mobile phone alert test
About 225 million electronic devices across the United States will wail and buzz Wednesday afternoon as the Federal Emergency Management Agency conducts an emergency alert test. A tone will sound at 2:18 p.m. EDT, similar to that of an Amber Alert or flood watch warning, and the subject of the alert will read: "Presidential Alert" and text will say: "THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed."
