CMAS/WEA uses SMS Cell Broadcast. I assume the SMS firmware on the phone
has to know what to do about those, and I don't know how far that knowledge
goes back in the deployment of SMS firmware, and it's all-fired difficult
to find out, IME.
Anything built in the last 4-5 years certainly should know; I've received
CMAS on phones as far back as 2009 build or so... though I did need an app,
and I had to steal one from another carrier than my own.
Cheers,
