Cell phones across the nation will start buzzing simultaneously on Wednesday, Oct. 3, around 11:20 a.m. Pacific time, as FEMA tests its national emergency alert and notification systems.
The test message will have a header that reads “Presidential Alert” and text that says, “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”
