MBIM_STATUS_MS... status codes are not recognized
MBIM status codes are defined in Section 9.4.5 of the MBIM standard. In addition, the following additional failure status codes are defined:
Status Code Value (hex) Description MBIM_STATUS_MS_NO_LOGICAL_CHANNELS 87430001 The logical channel open was not successful because no logical channels are available on the UICC (either it does not support them or all of them are in use). MBIM_STATUS_MS_SELECT_FAILED 87430002 The logical channel open was not successful because SELECT failed. MBIM_STATUS_MS_INVALID_LOGICAL_CHANNEL 87430003 The logical channel number is invalid (it was not opened by MBIM_CID_MS_UICC_OPEN_CHANNEL).
Now we have these statuses Unknown:
