While probably better than relying on mobile towers, aren't satellite communications difficult with a dense forest canopy? Probably best that people be aware of the limits of their devices before heading out.

Easier to climb a tree or find a clearing than hike 600 miles to the nearest cell tower, right?

Climbing a 100+ foot tree would probably not be advisable or possible in an emergency situation. There may not be a nearby clearing or you could be disoriented.
Likely the satphone is better, but there are still limits.

Why not? There are all kinds of Emergencies. Some trees are fairly easy to climb.

You do need some level of line of sight to the sky for Iridium voice, less so for sending SBD (similar to a text message).
If your GPS can get a fix, you can probably find enough signal to send a SBD.
Iridium carrier signal is stronger than GPS.
