Can i turn my iphone 5s into a prepaid phone?

Can I turn my iphone 5s from Verizon into a prepaid phone. Thinking about buying a Att go phone SIM card and use that.

You've to get the phone unlocked first before you can use the phone on AT&T. Check online for factory unlocking the iPhone 5S and then use the phone on AT&T. You can also email me if you need help in unlocking, I can suggest you some.
