is the user who started wvdial in group dialout and is the modem tty own by group dialout? You can check what groups you are in by using the command 'groups'. If the usre is not in the group dialout, as root do 'vigr' which reads $EDITOR if you do not want vi and add the user to the line dialout. Then log out and log back in.
