A Straight Talk refill card is a way to replenish a Straight Talk service plan. When consumers purchase a cellular service plan through Straight Talk, they must refill their balance at least once every month. Users can purchase Straight Talk refill cards or sign up for an auto-refill option that charges a credit card.
A refill card allows Straight Talk customers to continue placing phone calls, sending texts and using data. When customers enroll in auto-refill, they no longer have to purchase refill cards, which might be easier for some consumers. Refill cards can be purchased at Wal-Mart retail stores.
