Are satellite phones under the same microscope as cell phones? Are they broadcasting on all the different cell/wifi/bt frequencies or do they just connect to a satellite? Are they GPS tagged?

Also if you want one-way “location less” communication, the old alphanumeric pager network is still available.

I think those messages are simply broadcast across the network (which at least in the US is national). There’s evidence of a message being sent, none about whether it was received or where it was received.
