Wednesday will be the second time the test includes all cellular devices, the release stated.
Testing will start around 2:20 p.m. Eastern Daylight Time and will last for about 30 minutes, according to the federal agency. The message will read, “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed,” and will be sent in English or Spanish, depending on the device’s language settings.
“The purpose of the Oct. 4 test is to ensure that the systems continue to be effective means of warning the public about emergencies, particularly those on the national level,” the release stated.
If the Wednesday test has to be canceled because of “widespread severe weather or other significant events,” it will be rescheduled to Oct. 11, according to FEMA.
