Wireless Emergency Alerts (U.S.)
Wireless Emergency Alerts, also known as CMAS or PLAN, is a U.S. national
emergency alert system. Emergency alerts can pop up to tell you about a
national or local crisis. After you close an alert, you can reopen it. Swipe up from
the home screen and tap Settings > Notications > Wireless emergency
alerts.
Tip: Emergency alerts have a special sound and vibration that is two seconds long, followed by one
second, then another one second.
To choose which types of alerts you receive, swipe up from the home screen and tap Settings >
Notications > Wireless emergency alerts. The U.S. and local governments send these alerts
through your service provider. So you will always receive alerts for the area where you are, and you
won’t receive alerts if you’re outside of the U.S.
