The National EAS and WEA test will be held on the backup date of October 3, 2018, beginning at 2:18 p.m. EDT.
Cell towers will broadcast the WEA test for approximately 30 minutes beginning at 2:18 p.m. EDT. During this time, WEA compatible cell phones that are switched on, within range of an active cell tower, and whose wireless provider participates in WEA should be capable of receiving the test message. Some cell phones will not receive the test message, and cell phones should only receive the message once. The WEA 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.”
