Ok, new to smartphones...and taking a cruise in a couple months. A guy at work is trying to explain things to me as we run into each other. He says that if i setup a Google Voice # (I have) and get sipgate (I have) and download Fring (I have) i can pair google voice with sipgate, and call my google voice # through Fring (with Sip) over Wifi while on the cruise to make free calls. Is this true? I really havent done anything with Sipgate except set it up in Fring. If so, what do i do in Sipgate to pair with Google Voice? Then how do i use it? Is there another way? Or am i (or was he) way off base? He travels internationally and said he has been doing a lot of research lately. Anyone? I appreciate it!
