I'm doing an upgrade swap with my mom. I called AT&T, but I got conflicting statements. One woman said she didn't even know they were going to be using micro-sims until a customer told her, & the other said I would need to buy a new one. I don't want to be SOL because I can't buy another micro-sim due to everyone else doing an upgrade swap purchasing them. I'm in a pickle. Anyone here have any knowledge? Thanks!
