If an emergency alert is not received, it could be due to several reasons including: the alert not being sent by local authorities, phone settings not properly configured to receive alerts, being on Wi-Fi instead of cellular network, software or carrier settings needing an update, phone model not supporting emergency alerts, or poor cellular signal in the area. To address this, check that emergency alert settings are enabled on the phone, update the phone's software and carrier settings, restart the phone, and ensure the device is connected to the cellular network rather than Wi-Fi. It is also important to verify with the wireless carrier that the phone is capable of receiving these alerts and that the service is active. If alerts are still not received, contacting local emergency services or carrier support for troubleshooting is recommended. Other sources of emergency information include NOAA Weather Radio, TV/radio broadcasts, and alerting apps.
