When I attempt to set Google Voice for my voicemail I get a message stating: "Carrier configuration Unfortunately your network carrier is currently not supported for automatic voicemail configuration. To use Google Voice as your voicemail provider, please visit the Google Voice Help Center for more information." Of course the help center offers no help for this issue. Note, I did a number port from US Cellular to Sprint, I'm not sure if that is the source of the problem. I did deactivate my Google Voice voicemail and then activated it again with Sprint labeled as the carrier. Still nothing. Any ideas?
