IPhone 5 free carrier unlock?

Where can i get my iphone 5 unlocked with out paying?

You simply can't get it for free. Unless you have possibly finished your contract if you have one, then they might unlock it for free.
was the phone bought outright or is it still in contract. What service provider do you use

I have not yet come across any free unlock for this model. I suggest you can approach your network provider where they may offer free unlock if all their terms and conditions are satisfied. If they deny then you need to pay for the unlock of your iPhone 5. You can approach any legit unlock service like http://www.unlock-zone.com/apple-iphone-5/rs5wp9/ and get their permanent remote unlock service.
