I have three lines with Verizon, all of them on the unlimited plan. I will be upgrading two of these lines. I have been told that I need to change the plan for those lines and for the same price as the unlimited I will receive 6G of data which is more than enough. Currently, those lines use less than 1G each. So even though it's plenty for now I am concerned that down the road Verizon will change the plans. Is there a way to keep unlimited all of the plants? The third line upgraded to a 5s last year.
