I'm actually from Utah (just moved from there a few years ago). My brother-in-law goes to Moab all the time with his Verizon phone and gets coverage. I've been to Kanab with mine and it worked great. I would suggest a car charger for sure - especially if you're worried about it draining. If you're REALLY worried about your battery, I would also get an extra one with the battery charger and car charger. You can charge your spare battery while using the other. When the one you're using dies, just swap with the charged battery (that's what I do). Here is a link to the battery charger I'm talking about

Hope this helps.
