Instead, could we hook up eQMI_WDS_GET_MODEM_STATUS and the eQMI_WDS_MODEM_IND indicator or something and watch sWDSModemStatusReportIndication_Status to see if we're already connected or when we get disconnected? Maybe it sends that indication instead of packet service status for the NDIS autoconnect or something. Worth a look perhaps. It's just that we could get call failures from so many places and checking them all seems icky...
