The logical channel number is invalid (it was not opened by MBIM_CID_MS_UICC_OPEN_CHANNEL). The logical channel open was not successful because SELECT failed. 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). In addition, the following additional failure status codes are defined: Status Code MBIM status codes are defined in Section 9.4.5 of the MBIM standard. See each CID’s individual section within this topic for more info about its parameters, data structures, and notifications. The following table specifies the command code for each CID, as well as whether the CID supports Set, Query, or Event (notification) requests. These extensions do not include any new uses of device service streams. The Microsoft extensions comprise a set of device service commands (both Set and Query) and notifications. This topic describes a set of Microsoft extensions to MBIM that describe this additional functionality at the MBIM interface. One of the features the RIL provides is an interface for low-level access to the UICC. In a mobile broadband-enabled Windows device, the MBIM interface is used in addition to the Radio Interface Layer (RIL) interface.

These additional capabilities include support for a secure element for mobile payment solutions based upon near-field communication, or for remote provisioning of an entire UICC profile. However, the smart card may have additional capabilities beyond those that are defined by the MBIM interface. The Mobile Broadband Interface Model Revision 1.0, or MBIM1, defines an OEM- and IHV-agnostic interface between a host device and a cellular data modem.Īn MBIM1 function includes a UICC smart card and provides access to some of its data and internal state.
