On the glider retrieve with the pilot the next day we found that there was excellent coverage with Verizon. You could see the tower.

I was unaware that you could use an emergency call function to get out of network. I have been at the southern part of the Everglades with no verizon coverage (there is some attention coverage) and had no roaming option. Any idea how to start an emergency call. From a lock screen?
