Yes, understood. That wouldn't be my problem.
If I am at work and my wife is at home, we are both on wifi. If I call/text my wife with Viber and she has left home to run to the store, I want to make sure that she would not pick it up on 3G while she is out and use up limited data. That is why I want to know if there is a setting to only use wifi.
