[Pimped Out 4 LYF]

ive been there so many times, im getting sick of the m-life logo. Anyways i just want to know, how much do you have to pay, whats the min. amout so that all your minutes are usable again. Say you have 5 dollars worth of minutes left but they are going to expire in a week. If you add a 1 dollar increasment, do they all come back or do you need to buy a new phone card to get them all back? Im a little confused about that. Any1 that have a prepay phone know??
