Our family plan gives us 700 minutes between the 4 of us, then unlimited text. But we never use the 700, so we have tons of rollover minutes. XD I don't remember how much it costs.
I used to have a Tracfone, but then my parents told me that it was only like $5 a month to add me on to theirs, while I've been paying for minutes for like 6 months because they're too lazy to add me.
