Going from a 3g phone to a 4g phone

Ask them before you do it. Coworker of mine bought my old Bionic to replace her LG Android phone and they moved her to a 2GB plan when she activated it. Told her it was because she moved to a 4G phone

Go ahead and ask them, but you just have to tell them not to change you're plan. The computer automatically tried too change my plan to the 4 gigs for 2 gigs promotion. But i "nicely" made sure the agent knew i would be extremely angry if my unlimited went away
