What prepaid phone plan can I use with my iphone 5c?

I have an iphone 5c that I used on sprint, the person who I had a contact with cancelled her plan. I don't want to sign up for a contract with sprint and am shopping for a prepaid plan. Is there a prepaid plan that I can use my iphone 5c from sprint with? Straighttalk doesn't work unfortunately

You can get the phone unlocked and use it on StraightTalk / SimpleMobile / MetroPCS / Net10. You can also get the phone flashed to MetroPCS / Cricket / US Cellular / Virgin / PagePlus. It all depends on where you're located and which prepaid service has best coverage there. If you need help with getting the phone flashed or unlocked, mail me for references.
