Im going to buy a Galaxy S 3 originally for sprint. If I unlock it, can i use it on a prepaid plan that works on AT&T's network or on T-mobiles network?
â€¦the prepaid plan i am going to use will be one of these
Straight Mobile(T-Mobile network),
Yes but to other sprint related companys. There is a way to flash that on a computer using odin or something. I dont remeber. Just goto youtube. But the companys are Boost mobile, and Virgin mobile. I like virginmobile to be honest. Good Luck!
