i just bought a galaxy s3 and it is a Verizon phone(craigslist) and i wanted t-mobile for my service so i went to t-mobile and i got the service but all i can do is call and text but I'm paying for call, text, and data so is there a way i can get data on my phone because i can't use internet unless I'm at wifi and i don't want to switch to Verizon
