Is there a app for iPhone that allows you to video chat with 1 Internet connection?

Is there an iPhone app that allows you do video chat or call someone but only 1 person needs and Internet connection. I want to video chat my girlfriend but her Internet is turned off but I have Internet Please Help

Think about this…

Quite simply no.

There are only two types of connections, open and closed.
I envision a pretty wide open connection between you and a person with no internet service…

It is like if your phone works and hers doesn't, you can't call her. If you love her, buy her a "mifi" so you can "connect"

NO, that makes no sense does it… APPS are programs not magic. If she can get free Wi-Fi somewhere, like a coffee shop or mcdonalds then you probably can.
