How to buy an Iphone at Cricket?

My contract with Verizon just ended and I can no longer afford their service, I want to go to Cricket and get the Iphone 5c without spending hundreds of dollars each month. I seen on the Cricket website that an Iphone is 499.99 after discount and the smart plan would be $50 a month, My question is, Do you have to pay the full price for the Iphone and then the monthly charges, or do I get the phone at a discount like at Verizon?

You pay for the phone completely, but the monthly bill is a lot cheaper then verizon.

You must pay full retail price for your iPhone of $500 (no discount like from verizon) plus $50 a month but you have no contract, you can cancel at any time with no extra fees.
