You fundamentally misunderstand the technology. For push notifications and amber alerts and such to work, you need a personal 1:1 digital connection to a nearby cell tower. The range on that connection is not very far, and every alert needs to be sent individually.
An FM tower could broad-beam disaster information for tens of miles around with much simpler technology, out of one location on generator power. It is a far more reliable way to get information about a major disaster out to everybody simultaneously with far fewer infrastructure layers involved. No need to spool literally millions of alert pings out.
Also a continuous voice stream carries a lot more info than a damn push notification - obviously.

The alerting system in the US can broadcast them.
