M: Free? Nothing"s ever free.
W: Well, the phone is free.., after a $5 mall-in rebate.
M: Ah, so that"s the catch. And why do you need a cell phone anyway?

I can use it to call you in case the car breaks down.

1,000 free weekday minutes nationwide, and unlimited weekend minutes. Plus, unlimited, anytime minutes for anyone using the same service.

a dozen months.
