How much will the iPhone 6 really cost me?

I've done some research and apparently through AT&T I'd need to pay far more than 199 but is sounds like it depends on your situation, so here's mine;
I have an upgrade available and I don't plan on using any data. At all. That might sound crazy but trust me, I have my reasons. I want to now how much it will cost and if there's an extra monthly payment or something like that

Then you are leaving ATT is what you have decided. No cell phone company in America with post paid plans will sell you a phone without a data plan. That is how they make truckloads of cash so you pay to play or get off the playground. You will be buying the unlocked (carrier free) 6 16gb from the Applestore that starts at $659 and then loading it with minutes cards from a Walmart for GOphone or something. Best luck.

You will be paying the FULL price of the phone if you pay it all up front.

You will be paying the FULL price of the phone if you pay it over 24 months (making it a contract)

You will be paying the FULL price of the phone if you pay it with a upfront down payment of ANY Dollars, and the rest over X number of months. (also a contract until it is fully paid off)

Remember whatever the phone's full price is today, will be less by the end of 24 months, so you will be locked into the full price the day you get the phone. The price will go down the first of the year a few bucks, around spring break or before summer break, again right around before school starts (sales and promos) and fall and the holidays when things go on sale again, and if another version comes out.

DO NOT BUY IPhone 6 get the 5s

Ask your carrier for the most accurate answer.

It costs $199 plus all applicable taxes. You have to have a data plan if you get a smartphone.
