About emergency and government alerts on iPhone

You can receive emergency, government, and public safety alerts on your iPhone. In the event of an emergency, your iPhone might display:

• Alerts issued by your country or region's government
• Alerts involving imminent threats to safety or life
• Alerts for extreme weather conditions
• AMBER alerts (America's Missing: Broadcast Emergency Response)¹
• Public Safety Alerts¹

You can also receive emergency, government, and public safety alerts on your Apple Watch.

1. AMBER alerts and Public Safety Alerts aren't available in all countries or regions.

By default, Government Alerts are turned on for your device.² When you receive a government alert, you hear a special sound that's similar to an alarm. If you want to turn these alerts on or off, follow these steps:

1. Go to Settings > Notifications.
2. Scroll to the bottom of the screen.
3. Under Government Alerts, turn the type of alert on or off.³

2. Government Alerts are supported when using a SIM card from a supported carrier. For more information, contact your carrier. 

3. In some countries or regions, you may not be able to disable Government Alerts.

When your iPhone is connected to a carrier in the United States—using a U.S. SIM or while roaming in the U.S.—you can enable Test Emergency Alerts. By default, this is turned off. When you receive this type of alert, you'll hear a sound that's similar to an alarm, and the alert will mention that it's a test.

Government test alerts are available with U.S. carriers, including Puerto Rico. Your local government is responsible for the content and the frequency of the test alerts. You can disable this feature anytime with the following steps. For more information, contact your carrier.
