The DLT (Distributed Ledger Technology) error codes for the Vodafone Idea (Vi) platform (VILPOWER) are the standardized set of universal DLT codes used across all Indian mobile network operators. These codes are primarily in the 6XX series and denote failures during the mandatory DLT scrubbing process.
Vi's documentation often explicitly mentions the meaning of these standard codes, sometimes adding a specific internal marker like {VI:I} to denote an inactive status on their platform.
