Try tripadvisor, probably more people who would know on there.
I was in Nevada last month and there were those little shops/stalls selling "mobile accessories" in all the usual shopping centers. I never asked about SIM cards - big mistake. Got stung for huge data charges. Also consider buying a phone over there? Pawn shops very popular.
"but what I have discovered works is buying the cheapest AT&T Gophone phone from Walmart (about $20), putting the sim into my android phone and activating it. It has worked every time. The cheap phone goes in the bin."
