Today I downloaded the google voice app and tried to set it up. However, after putting in my voice mail pin, it cannot verify my phone number; Why is that?
I believe, like all relatively new Google programs, that GV too will be on an invitation only basis in the beginning. There are some forums I have seen that provide invites from users already using GV. I did some looking since I had the same exact problem as you.
yeah n1caboose is correct you need an invite you can go to the google/voice site and request an invite or its a thread in the General Discussions "google voice" people post when they have invites to send to people. You might want to try that.
