Hey everyone..so i just got this new Samsung galaxy s3 and it is fckin awesomeeee

Only thing it is kinda slow when loading internet sometimes and stuff..but i think i know why..it is currently on 3g..with my plan and this kinda phone I'm pretty sure i should be on 4g...

My question is...how do i switch this thing from 3g to 4g?????
