Perhaps you should set this to find out what's going on both when
you have success and failure, to see if there's a difference.

IIRC (15 years) wvdial uses ppp. I know that ppp can be made to log
debug information. I can't remember whether wvdial does. (I never
used it but I helped occasionally.) So once again you need to look
at the logs when it works and when it doesn't.
