E_MBN_INVALID_CACHE
E_MBN_INVALID_CACHE is a Windows Mobile Broadband (MBN) HRESULT. It indicates that the Mobile Broadband visible-provider cache cannot be used for the requested operation.
What to check for E_MBN_INVALID_CACHE
- Refresh provider information from the device instead of selecting a provider from the stale cache.
- Check for changes in radio state, location, SIM, roaming status, or device reset since the cache was built.
- Keep cache invalidation separate from provider-selection logic so a refresh failure is visible in diagnostics.
Diagnostic interpretation
This result has the HRESULT value 0x8054820C. AllStat records the condition as “Visible provider cache is invalid.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the mbn / cache operation.
- Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original mbn / cache condition.
