The most common reasons for not receiving an emergency alert on a phone include:
- Emergency alerts not enabled in phone settings (check under Notifications or Wireless Emergency Alerts).
- Phone device turned off, in airplane mode, or connected to 2G/3G or WiFi-only network.
- Device not compatible or needs software updates (iOS 14.5+ for iPhone, Android 11+ for Android phones).
- Location services or registration for local alerts not set or required separately.
- Carrier or government alert system issues or restrictions.
Checking and enabling emergency alerts in phone settings, ensuring the phone is compatible and updated, not in airplane mode, and registering for local alert services can help ensure alerts are received. Sometimes alerts are issued based on location, so location settings may also matter.
