Can I use my iPhone 6 on a prepaid plan?

I have a sprint iPhone 6 and I wanted to get it unlocked but I don't know how. So my other option is to get it on a prepaid plan. And how do prepaid plans work?

You can use a prepaid cell phone plan. I recommend Kajeet. They allow you to bring your Sprint phone to their company.

Prepaid cell phone plans take the money from you up front and then you are given minutes and service days. With most prepaid cell phone plans you purchase a airtime card then use a computer, another phone or your prepaid cell phone to add the airtime card to your service. Some prepaid cell phone providers allow you to have the money removed from your checking account each month, so you don't have to worry about purchasing an airtime card and adding it each month.
