AT&T buy out Alltel in South Dakota and I was wondering if I could get the same unlimited data plan that I have with AT&T or not? I've talked with both AT&T and Alltel with both of them saying oppsite things. Alltel said I would be "grandfathered" into AT&T with my existing account so I could keep my unlimited data on a smartphone, but when I called AT&T about this they said that existing customers would be migrated into AT&T and would have to choose one of their data capped plans. I'm just figure out who is right and if I have to switch carriers when AT&T comes because they won't let keep my unlimited data plan.
