About emergency and government alerts on iPhone and Apple Watch

You can receive emergency and government alerts on your iPhone and Apple Watch. In the event of an emergency, here's what you might see:

• 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)*

*AMBER alerts aren't available in all countries or regions.

By default, Government Alerts are turned on for your device.^* 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 very bottom of the screen.
3. Under Government Alerts, turn the type of alert on or off.^*

*Government Alerts are supported when using a SIM card from a supported carrier. Your Apple Watch can receive these alerts if your iPhone can receive them and is nearby, or your Apple Watch is on a Wi-Fi network. With a cellular plan from a supported carrier, your Apple Watch Series 3 (GPS + cellular) can receive these alerts without your iPhone nearby. For more information, contact your carrier. 

*In some countries, you may not be able to disable Government Alerts.
