Just got home from the Verizon store, where I went to ask questions about the trade-in I want to do tomorrow. However, I forgot to ask them: When I upgrade from an IPhone 4 to an IPhone 6, will I have to change the plan I have now? I am currently part of a nationwide family share plan with 2gb of data! I would like to keep my 2gb data plan and my monthly bill around the same price if possible.
