Hi There, I'm pretty sure I'm going to give T-Mobile a try with the next iPhone 5S release. I'm off contract, and I'm ready to switch. I'm going to get a plan w/ mobile hotspot, as I use that a lot, but I also might get an iPad Mini when the retina display version comes out. Am I able to add a data plan for that iPad mini onto my T-Mobile phone plan? I'd like them to be on a single bill.
