Pokemon Go Issues

Pokémon Go is played all over the world, hell even my Brony guys are playing it, but there one thing, well two actually, which is one: It has wifi connection and secondly is has DATA! and it cost so much money. Now I'm not saying I hate, I tried it with my friend's and it was ok but I would rather play Pokémon on 3DS instead of the app. Also I can't wait for Pokémon Sun and Moon aka Celestia and Luna oh and I didn't made this us it was my friends.
