I would like to upgrade to lightweight 45 from old 45 dollar plan. I was told I had to pay off my tab before I could upgrade my plan. the only difference between our plan is unlimited calling. Is this the same as if I was a new customer and not one that has been with you before the 2 year plans be came law. We have been devoted customers to you and we feel that it is not the same. If I pay off my tab My tab would go to zero. or are you looking for me to buy a new phone?
