If it's for public safety, don't cell phones already have a feature designed specifically for that purpose (Cell Broadcast), which works even when the user doesn't have a wired headphone plugged into the device?

I've never seen an iPhone displaying a CB message. Our mobile operator uses channel 50 to advertise network discounts, and iPhones don't display this, while many other phones do.

Does CB messaging work on iPhones?

To make a guess: Could "FM sender + charged phone" vs "cellular network + charged phone" availability be a relevant distinction?

I.e. Fm sender + Cell broadcast -> better bet hedging.
