Today, the FCC and FEMA will be conducting the nation’s first test of its wireless emergency alert system.
The test will take place on Wednesday, October 3, 2018, at exactly 2:18 PM EDT. At that time, your phone will make a loud noise and you’ll see a pop-up on your screen that reads:
Presidential Alert. This is A TEST of the National Wireless Emergency Alert System. No action is needed.
The alert won’t have any adverse effects on your wireless service or device, and after tapping the “Dismiss” button at the bottom of the pop-up, it’ll go away and you can carry on with your day like normal.
