The advisory follows a recent cybercrime investigation in Chhattisgarh, in which a Point of Sale (PoS) agent was found to have allegedly activated 25 SIM connections using identification documents of citizens without their knowledge and consent. DoT and telecom operators blacklisted the PoS agent. These mobile connections were examined on the Digital Intelligence Platform (DIP) of the DoT, and those identified as suspicious were subjected to re-verification. Connections which did not complete the verification process were deactivated.
