IF you lose cellular... (Out of range) I'd have the phone listen for a satellite and if it sees one it would display a message. It might even "handshake" with it and let you know if it gets and ACK or not.
Either they have tested the system and it works...or it doesn't. Providing you feedback in a non-emergency is not required and may degrade the operation.
The problem is if you have a million phones trying to do a handshake once a minute on a very limited capability system, there may be no bandwidth when there is a real message to send.
