Can you FaceTime on a iPhone 4S without Wi-Fi?

I would like to know if you can FaceTime without Wi-Fi on a iPhone 4S. I know some carriers don't allow it but I have sprint so i don't know if I can.

Yes you can FaceTime without Wi-Fi… But need to have iOS6 n above.

I believe you can though I wouldn't recommend it. You'd be using 3G in that case and that is a pretty expensive option to do a video chat
