Yes, you can use that balance until it goes to zero. However, you have to make sure to use the balance before the expiration date, if you don't, make sure to refill the account with some more money to extend the expiration date, so you can keep the money on your account, and keep it rolling. 

Sorry, but I don't think you got the question.

I would like to use my balance to pay the $25 every 3 months instead of adding money via a credit card to extend the expiration date.

I know I can use it for minutes, text and data so why can't I use it to extend the expiration date?

If I have $250+ in the account that should cover about 30 months of service at $25 every 3 months.
