this seems to be a common problem , though most seem to solve it half way through thread and leave without saying how
i have a smartlink installed, drivers installed and modprobed etc. and my wvdial.conf file configured. wvdial shows the following:
-->WvDial:internet dialer version 1.54.0
-->Warning: internet section [nameofmyISP] does not exist in wvdial.conf
-->Initializing modem
-->Sending:ATZ
-->Sending ATQ0
-->RE-Sending:ATZ
-->Modem not responding
the warning on the second line refers to 'Inherits = <nameofISP>' in my wvdial.conf file but i dont think this is causing the modem not to respond.
