1. A computer-implemented method for providing alert messages to wireless devices through a telecommunications network, the method comprising:
receiving, by an alert broadcast system associated with the telecommunications network from an alert management system, a first alert message indicating an emergency,
wherein the first alert message includes a unique identifier associated with the emergency, and
wherein the unique identifier is generated by an alert message originator associated with the first alert message;
forwarding, by the alert broadcast system, the first alert message to a first group of wireless devices,
causing, by an act of the alert broadcast system of sending of the first alert message, a software application at each of the first group of wireless devices to temporarily store the unique identifier at the first group of wireless devices;
receiving, by the alert broadcast system of the telecommunications system from the alert management system, a second alert message associated with the emergency,
wherein the second alert message includes the unique identifier,
forwarding, by the alert broadcast system, the second alert message to a second group of wireless devices,
causing, by an act of the alert broadcast system of sending of the second alert message, the software application at a respective wireless device of the second group of wireless devices to determine, based on the unique identifier, that the respective wireless device has received the first alert message prior to receiving the second alert message and that the second alert message is partly duplicative of the first alert message; and
causing the respective wireless device to perform an action based on the determination that the respective wireless device has received the first alert message prior to receiving the second alert message and that the second alert message is partly duplicative of the first alert message.
