what is the status of USSD support in libqmi? AFAIK it would be about the same complexity to implement in libqmi as it would be implementing it in libmbim (except MBIM is an open standard). Seems to me that different vendors implement USSD using AT-commands in different ways. :-/

AFAIK USSD is like advanced session-based flash-SMS, setting up 1 and only 1 session at the time with the operator for different services.

However encoding is not defined by the GSM standard making MBIM and QMI interested... I know some quirks have been made to MM to get it working.
