OID_WWAN_PIN_EX2
OID_WWAN_PIN_EX2 sets or returns expanded information related to Personal Identification Numbers (PINs). OID_WWAN_PIN_EX2 is similar to OID_WWAN_PIN_EX, but extends it to support multi-app UICC cards.
Query payloads contain an NDIS_WWAN_PIN_APP structure specifying the target application ID whose PIN is being queried. Miniport drivers must process Query requests asynchronously, initially returning NDIS_STATUS_INDICATION_REQUIRED to the original request before later sending an NDIS_STATUS_WWAN_PIN_INFO status notification containing an NDIS_WWAN_PIN_INFO structure that describes the PIN for the application.
Set payloads contain an NDIS_WWAN_SET_PIN_EX2 structure specifying the PIN action to take for the application. Miniport drivers must process Set requests asynchronously, initially returning NDIS_STATUS_INDICATION_REQUIRED to the original request before later sending an NDIS_STATUS_WWAN_PIN_INFO status notification containing an NDIS_WWAN_PIN_INFO structure that describes the PIN state for the application.
Remarks
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 OID_WWAN_PIN_EX2 supports.
Just like OID_WWAN_PIN_EX, with OID_WWAN_PIN_EX2 the device only reports one PIN at a time. If multiple PINs are enabled and reporting multiple PINs is enabled, then miniport drivers 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 is specified by setting the PinSize to zero (0). In this case, a Set request 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.
