E_MBN_PIN_NOT_SUPPORTED
E_MBN_PIN_NOT_SUPPORTED is a Windows Mobile Broadband (MBN) HRESULT. It indicates that the selected Mobile Broadband device or SIM does not support the requested PIN operation.
What to check for E_MBN_PIN_NOT_SUPPORTED
- Query PIN capabilities and types before presenting or issuing a PIN-management command.
- Check whether the target uses an eSIM or a PIN type that is not exposed through this API.
- Use the carrier or device-management workflow for operations that the modem does not support programmatically.
Diagnostic interpretation of E_MBN_PIN_NOT_SUPPORTED
E_MBN_PIN_NOT_SUPPORTED has the HRESULT value 0x8054820F. AllStat records the condition as “Pin is not supported.”. For E_MBN_PIN_NOT_SUPPORTED, in practice, interpret that wording at the boundary owned by the Windows component or COM interface that returned the HRESULT, rather than treating the value as a generic Windows message.
Evidence to capture for E_MBN_PIN_NOT_SUPPORTED
- Record the exact COM method or Windows API, its input object, the calling thread, and the full 0x8054820F value before a wrapper converts it to an exception or Boolean result.
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions E_MBN_PIN_NOT_SUPPORTED or the mbn / pin / supported operation.
- For E_MBN_PIN_NOT_SUPPORTED, check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
Retry and recovery for E_MBN_PIN_NOT_SUPPORTED
Retry E_MBN_PIN_NOT_SUPPORTED only when the owning API documents a transient state or after the condition described as “Pin is not supported.” has changed. For E_MBN_PIN_NOT_SUPPORTED, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
