I've had pretty good luck in remote areas while airborne. Apparently, SMS
works when voice calls are not possible. But then, in Colorado, cell towers
are located on mountain peaks. As I understand it, if SMS service is not
avaliable, the 'phone will hold the message until it is and then send it.
The message gets through even if not in real-time.

The only way to know if tracking works is to try it.

I'm a Verizon customer, and the only place I've been able to get my
phone to work in a glider above pattern altitude is in areas where SMS
does not work. Maybe that will change someday ...
