The following table specifies the UUID and command code for each CID, as well as whether the CID supports Set, Query, or Event (notification) requests. Microsoft Basic IP Connectivity Extensions The following OIDs have been defined to support UICC application and file system access. 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. A file under the card root (EFDir under the MF in the diagram) contains the application names and corresponding identifiers. Each ADF is identified by an application identifier that can be up to 128 bits long. Additional applications are effectively implemented as separate trees, each rooted in its own Application Directory File (ADF). The SIM defines DFs under the MF, one of which, DFTelecom, contains information common to multiple access types such as the common phone book. 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 UICC file system can be regarded as a forest of directory trees. The following diagram from Section 8.1 of the ETSI TS 102 221 technical specification shows an example card application structure. The SIM is a legacy portion of the UICC that can be modeled as one of these applications (for GSM). These include the USIM for UMTS, CSIM for CDMA, and ISIM for IMS.

The UICC provides a file system and supports a set of applications that can run concurrently.

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. This topic specifies an extension to the Mobile Broadband Interface Model (MBIM) interface to permit accessing UICC smart card application and file systems.
