How to unlocked sprint iPhone 5?

I want to unlock my sprint iPhone 5 to metro pcs or another carrier because I can't pay the bill from sprint and I don't care if it's illegal or legal I just want to unlock it. It's been off for awhile now I need help please

If you still owe money to Sprint, Sprint will blacklist the esn, blocking the phone from ever being activated again, on any mobile carrier. Unlocking the phone will not remove the bad esn that your phone has, assuming you still owe money to Sprint.

Sprint has to unlock the phone and is not going to do so if there's an outstanding balance on the account. I'm sorry, but you are out of luck. Even if you were to find someone who would unlock it illegally, a new provider is not going to activate it because it would be "blacklisted".
