Hello everyone! I have a quick question about using a 2 year upgrade on At&t for the preorder tonight. I currently have unlimited data and I want to use an upgrade on a different number on my account, however, the only upgrade I have available is under the line I have for my grandfather, which is just one of those cheap flip phones. My question is, would using the upgrade from this number force me to sign up for a data package? Or will there be an option to port the upgrade over to my line somehow? Thanks to everyone for your help!
