Modern GSM phones don't seem to get any coverage at altitude. When I
had my CDMA phone I could send emails when I flow over populated areas.
Now, nothing.

You don't have to go very high to be "at altitude" to not receive a
cell phone signal. Two years ago on July 4 at the top of the Stratosphere
tower in Las Vegas, I overheard several people remarkng how their cell
phones had roamed to analog to connect. My phone is CDMA and was not able
to pick up a digital signal, either on network or digital roaming while
analog roaming gave a solid signal. Excellent digital signal at ground
level.
