on Droid Bionic. I have an existing account and am trying to get google voice set up correctly. I always get the "network carrier not supported" error. My GV app on my Bionic sets my voicemail number to a "615" area code number, yet I can't change it to what shows up on my google.com/voice account settings ("406" area code). I've uninstalled, reinstalled, dialed *71 with both numbers I referenced above, and still get network error notices. Any help?
