Comment 17 for bug 864658

@Eshant, I don't think there is a bug in wvdial. I had the same problem. Applications like evolution and gwibber first check through network manager to see if internet connectivity is available. As network manager doesn't recognize the evdo modem, evolution and gwibber try to work offline. The solution is to uninstall network manager as I have done. Now connect to internet using wvdial and all your applications should work fine.
