Yes, it is cheaper. Do the math. You are paying $750 towards the phone itself, and a very high $115/month phone bill on top of that. If you went with a $45 SIM from Straight Talk, Virgin, or somebody like that, you would save $840 on service alone during the course of the first year—enough to pay for the phone.

Basically, because you are using AT&T, you are paying for three iPhones instead of one.

You still have to buy the wirelss phone and you get throttled (means you almost have no download speed to your phone) if you exceed 5gbs. Which is not that hard to do.

BTW, there is no difference in an unlocked iPhone 6 price wise. Here is the link from Apple.
