Moving question

I will possibly be moving to another state in November. When I get there, I will probably want to get a local number. Will I be able to keep my existing plan when I do this or will I have to get a new plan?

You will be able to get a new number local to where you are living. Just call them up and tell them your new address and they will assign you one at no charge, no change in plan, and no contract extenstion.
