True, but apparently Google is considering the option of limited two way satellite based communication. The OP didn't do a good job explaining it, but the article itself mentions a satellite text option, and a potential new feature that lets you update your location every 15 min with a max of 5 updates per day via satellite communication.
This would be useful for people working, hiking, camping, etc in areas with zero cell signal and no Wi-Fi. If something bad happens requiring emergency services, the phone could transmit your location to the satellite and make it available to others in your family/group to see exactly where you are.
What I wonder is if my phone has enough power to send a signal into space, why doesn't it have the power to send a signal to my local cell tower?
