The U.S. Federal Government is scheduled to send a message to all U.S. cellphones today, Wednesday, October 3, to test a previously unused alert system designed to warn the public about national emergencies.
The test message is scheduled for 2:18 p.m. EDT. It will have the headline "Presidential Alert", according to the Federal Emergency Management Agency (FEMA) which will send the alert. FEMA says phones will make a loud tone and have a special vibration. The message will read: "THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed."
The test has been scheduled to ensure that the alert system would work in the event of a national emergency. U.S. cellphone users will not be able to opt out.
