About emergency and AMBER alerts
In the United States, your iPhone and Apple Watch* can receive emergency and AMBER alerts. In the event of an emergency, here's what you might see:
- Alerts issued by the President or government agencies
- Alerts involving imminent threats to safety or life
- AMBER alerts
- Alerts for extreme weather conditions
In Japan, your iPhone and Apple Watch can receive Emergency Earthquake Alerts from the Japan Meteorological Agency. Learn how to set up emergency alerts for Japan.
Government alerts vary by carrier and iPhone model, and may not work under all conditions.
Turn Government Alerts on or off
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:
- Go to Settings > Notifications.
- Scroll to the very bottom of the screen.
- 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.
