No stands, but I did find myself completely bored and playing some games on my phone this year. (Sitting in an alcove in a rock face, watching a valley.)
Most of the area I hunt doesn't have any cell reception at all.
But, there was a logging company doing some work in the area this year, so they had a temporary tower set up. Hiking about half way up the mountain got me a pretty respectable signal from the temporary tower. It allowed me to get directions out to some down-on-their-luck hunters, so they could come meet up with me; and I sent a few text message status updates to the wife, over the week.
