If you upgrade with a discount after 6/28 you lose your unlimited plan...you're not forced into the family share, but can choose the tiered data plan that came what I believe last summer?
Only way you get to keep it after 6/28 is by paying full retail price for a phone
Right, but if I upgrade my feature phone to a smart phone and choose a tiered data plan my 2 other unlimited data lines are left alone. Then when I re-activate the feature phone on the line I just upgraded I can activate the new phone on one of the unlimited lines. Technically I'm not upgrading the unlimited line, I'm simply activating a phone I currently have on my line...
