Usually this is enforced at the cellphone carrier level. The US has the amber alert protocol which also has a function for the president to dispatch any message (and can only be used by the president iirc), and that level of message can't be turned off via settings.
Even in our best countries FB usage is never 100%, so cellphone / landlines makes a bit more sense.

This is the Wireless Emergency Alert system, which carries Amber Alerts, Alerts about imminent threats to life/safety, and Presidential Alerts. The last (and only the last) can't be disabled in settings, because the legislation requiring support for the capacity required that Presidential alerts not be disabled. (The system is basically the mobile-device equivalent of the broadcast Emergency Alert System.)
- flashman 11y agoI suppose I hadn't really thought about why they'd use Facebook when you can just message all the cellphones in a geographic area. Your reasoning makes sense.
