Overview

This topic specifies an extension to the Mobile Broadband Interface Model (MBIM) interface to permit accessing UICC smart card application and file systems. This extension to MBIM exposes logical access to the UICC's ETSI TS 102 221 technical specification-compliant applications and filesystems, and is supported in Windows 10, version 1903 and later.

UICC access and security

The UICC provides a file system and supports a set of applications that can run concurrently. These include the USIM for UMTS, CSIM for CDMA, and ISIM for IMS. The SIM is a legacy portion of the UICC that can be modeled as one of these applications (for GSM).

The following diagram from Section 8.1 of the ETSI TS 102 221 technical specification shows an example card application structure.

The UICC file system can be regarded as a forest of directory trees. The legacy SIM tree is rooted at a Master File (MF) and contains up to two levels of subdirectories (Dedicated Files, or DFs) containing Elemental Files (EFs) that hold various types of information. The SIM defines DFs under the MF, one of which, DFTelecom, contains information common to multiple access types such as the common phone book. Additional applications are effectively implemented as separate trees, each rooted in its own Application Directory File (ADF). Each ADF is identified by an application identifier that can be up to 128 bits long. A file under the card root (EFDir under the MF in the diagram) contains the application names and corresponding identifiers. Within a tree (the MF or an ADF), DFs and EFs might be identified by a path of file IDs, where a file ID is a 16-bit integer.

NDIS interface extensions

The following OIDs have been defined to support UICC application and file system access.

MBIM_CID_MS_UICC_APP_LIST

This CID retrieves a list of applications in a UICC and information about them. When the UICC in the modem is fully initialized and ready to register with the mobile operator, a UICC application must be selected for registration and a query with this CID should return the selected application in the ActiveAppIndex field in the MBIM_UICC_APP_LIST structure used in response.

MBIM_CID_MS_PIN_EX

This CID is used to perform all PIN security operations as defined in Section 9 of the ETSI TS 102 221 technical specification. The CID is similar to MBIM_CID_MS_PIN, but extends it to support multi-app UICC cards. Only single-verification-capable UICCs are supported. Multi-verification-capable UICCs that support more than one application PIN are not supported. One application PIN (PIN1) is assigned to all ADFs/DFs and files on the UICC. However, each application can specify a local PIN (PIN2) as a level 2 user verification requirement, resulting in the need for additional validation for every access command. This scenario is what MBIM_CID_MS_PIN_EX supports.

Just like MBIM_CID_MS_PIN, with MBIM_CID_MS_PIN_EX the device only reports one PIN at a time. If multiple PINs are enabled and reporting multiple PINs is also enabled, then functions must report PIN1 first. For example, if subsidy lock reporting is enabled and the SIM's PIN1 is enabled, then the subsidy lock PIN should be reported in a subsequent query request only after PIN1 has been successfully verified. An empty PIN is permitted together with MBIMPinOperationEnter. An empty PIN is specified by setting the PinSize to zero. In this case, a SET command is similar to a QUERY and returns the state of the PIN referenced. This is fully aligned to the behavior of the VERIFY command as specified in Section 11.1.9 of the ETSI TS 102 221 technical specification.
