WWAN_UICCSLOT_STATE enumeration (wwan.h)

  • Article

The WWAN_UICCSLOT_STATE enumeration lists the different states of a UICC (SIM) card slot on a modem. The slot state represents a summary of both the slot state and the card state.

Syntax

typedef enum _WWAN_UICCSLOT_STATE {
  WwanUiccSlotStateUnknown,
  WwanUiccSlotStateOffEmpty,
  WwanUiccSlotStateOff,
  WwanUiccSlotStateEmpty,
  WwanUiccSlotStateNotReady,
  WwanUiccSlotStateActive,
  WwanUiccSlotStateError,
  WwanUiccSlotStateActiveEsim,
  WwanUiccSlotStateActiveEsimNoProfile,
  WwanUiccSlotStateMax
} WWAN_UICCSLOT_STATE, *PWWAN_UICCSLOT_STATE;

Constants

 
WwanUiccSlotStateUnknown
The modem is still in the process of initializing so the SIM slot state is not deterministic.
WwanUiccSlotStateOffEmpty
The card slot is powered off and empty. An implementation that is unable to determine the presence of a card in a slot that is powered off reports its state as Off.
WwanUiccSlotStateOff
The card slot is powered off and a card is present.
WwanUiccSlotStateEmpty
The card slot is powered on but no card is present.
WwanUiccSlotStateNotReady
The card in the slot is not ready. In other words, it has been reset but has not finished initializing. It cannot be used at this time.
WwanUiccSlotStateActive
The card in the slot is available and ready to accept commands. This has no association with the SIM PIN locked state.
WwanUiccSlotStateError
The card in the slot is in an error state and cannot be used.
WwanUiccSlotStateActiveEsim
The card in the slot is an eSIM with an active profile, and it is ready to accept commands.
WwanUiccSlotStateActiveEsimNoProfile
The card in the slot is an eSIM with no profiles or active profiles, and it is ready to accept commands.
WwanUiccSlotStateMax
The maximum value for this enumeration.

Remarks

The set of reported states is constrained by the capability of the slot hardware. In the most restrictive case, the slot hardware may only be able to determine that a card is present when it is powered on and active; in such a case the OffEmpty and Off states will not be reported.
