Verizon S3 on AT&T network?

No, the rezound has it built in. I'm NOT saying that the s3 does. Just try a att sim card and see if it works. If it don't, sell it(can get around $400 or so) and grab one for at&t

What all did you have to do to get your vzw gs3 on AIO? I have the same phone and ready to ditch vzw but want to make sure AIO will work first. So I'm guessing you get HSPA+ speeds but not 3g or LTE? thanks

Neither, will only get 2G Edge.
