Right, but they're confusing. They don't give you a $$ credit, they give you a number of free messages (sent or received) and minutes (sent or received), but then you have to pay extra for "long distance" calls (whatever that means, I've never worked it out), you get (depending on your plan) extra in-network minutes, nights and weekend minutes, etc. It's really not set up for it to be obvious to consumers.

Also in my bill there are 13 separate taxes and tariffs that total about $17 that's on top of my monthly fee and usage.
