Been using skype and viber for almost 2 yrs. now. But calling my gf using those app. gives me headache. And sometimes pissed me off. I just wanted a hassle free app for international call. Any suggestions?

What about them, is a problem. I have tried several over past couple of years and always go back to skype.

Hi Fr_Chuck! It's a better app before I don't know what happen. Is there something to do with the location of the person I'm calling?
