Is there a free video call app on iPhone?

I'm looking for a free app or something similar like face time where you don't need Wi-Fi or Internet access?

Skype

You'll always need internet access lol, or at least 3G, just use Skype on iPhone.

They have Skype and OOVOO but they require either internet access or a data plan. Unless you have unlimited data that is not recommended nor any other video caller.

OoVoo
Tango
Skype
Hangouts
