I have three lines on my family plan and I am the only one with an iPhone 4, a data plan, and a contract (which expires next year). I was considering early upgrading my line or using one of the upgrades from my other lines (which are full upgrade pricing) and using it on my line and handing my younger sister my iPhone 4.
My question is: If the iPhone 4 is already activated and I pop in a SIM card from one of my other non-data plan lines (with data off), will they automatically put a $15 data plan on that line?
