i don't know how prices compare... as a legitimate old fart i use consumer cellular, $25 @month... i don't know what my limits are but i use voice, data (maps - a lot), and browse, (when I'm out and in need of nearby and restaurant info type stuff).
it seems pretty cheap to me - my significant other pays a good bit over $100 for 2 lines, but then she has an apple phone. Me, I have as low a priced android I can get that has the features I need (64g mem) - runs software, text, etc. and cost less than $100, 3 years ago.
