Sorry if this has been answered, but i did a search and read through multiple threads and im still not understanding or getting a complete answer. I just got my google voice invite. I choose to create a google voice number. My google voice number forwards to my cell phone number. I downloaded the google voice app. I choose "ask me to use google voice number when dialing". My questions is: 1) If i use my google voice number to dial out, am i truly using only the google voice number, or does it forward to my cell number and then dial out? In other words, am i getting charged for outgoing phone calls when i use my google voice number to place calls on my droid? I originally thought that google voice was for wifi. Therefor, if i am on a wifi network, i could place and take calls through the google voice app for free. I guess i don't fully understand how integrated it is with the droid. I now understand that if people call my google voice number, it just forwards to my cell and I will be charged, but i dont understan how it works dialing out.
