Yes, we get a discount.  You're talking a few dollars a month from what I get verses what you'd receive.  You do have to get the data plan, but it's added to the plan in a way it's not that much more than typical plans.

Here is my plan.  Notice we have the 700 split plan, but below you see they give us 200 bonus mins a month FOR FREE, which gives us 900 a month to split.  Plus we have like 3000 rollover mins, so we are golden.
