Fair enough; I didn't read your comment very closely, I guess. Terrestrial radio seems a lot less expensive in areas with population. When you get out beyond rural and more into wilderness, satellite is likely cost competitive, because having a LEO constellation cover the wilderness comes at no additional cost, and having radio coverage in the wilderness involves setting up base stations with low usage --- you can do some things with longer range / larger cells, but it depends on terrain and maybe protocol limits? GSM had a concept of 'timing advance' that effectively limited the maximum cell size, but I don't know if that's a limitation if you're not using TDMA.
