About emergency alert messages

If your wireless service provider or administrator participates in CMAS, you might receive emergency alert messages in your message inbox or your emergency alert message inbox on your BlackBerry smartphone. CMAS is an emergency alert network that can send presidential, imminent threat to safety of life and amber alert messages. Depending on your smartphone model and wireless network, this feature might not be supported. For more information, contact your wireless service provider or administrator.
