I'm just a layman guessing, but I'm thinking Amber alerts and Flash Flood warnings... or the Hawaiian nuclear strike

I thought the Wireless Emergency Alerts protocol was completely separate from SMS though, since it is based solely on geographic location of the cell tower and not your phone number.

They are entirely separate from SMS, you are correct. WEA messages are sent inside System Information Blocks (SIB12 specifically). Other SIB blocks are how your phone learns of authorization to use the tower, what frequency channels to use, neighbors of the tower, and other control related info.

At least on Andriod, I've got an "Emergency Alerts History" where I can view those. Does that count as being saved automatically?
