There isn't any, at least the last time we we're there. Around Horsetheif campground (BLM) on Hiway313 is where we could get cell phone signal, we have AT&T service.
I also have Verizon. I was told that the cell phone tower for the Moab area is on the La Sal Mountains just to the east. Whenever I am in the area I get good cell phone reception as long as I have a good view of the mountains.

We had a weak but usable Verizon signal at site E-15 last year.
