Hello all, My parents and I are all on one shared AT&T account, but with 2 plans however. I have my existing grandfathered unlimited data plan from way back in 07. My parents however got iPhones later (around the 4S) and are on a plan together. They originally had 2 year contracts, but now when they upgrade, they're prompted to use AT&T Next. If my parents upgrade via AT&T Next, will this affect my unlimited data account in anyway? Any feedback is appreciated.
