Can you change an iPhone's carrier from Sprit to Verizon?

I have an iphone and it's service is turned off right now. It's a Sprint iphone, but is it possible to change the iPhone's carrier to Verizon? I know they would probably be an activation fee or something but that's okay.

Sure you can, but it illegal lol, no one really cares though you would have to get someone outside of the phones companies to do it

You can't do it officially. You've to get the phone flashed to Verizon. If you want to get your phone flashed, email me for references.
