BSNL has launched home delivery of SIM cards, allowing customers to complete self-KYC online through its official portal. Available for both prepaid and postpaid connections, users can initiate the process by visiting the following link: https://sancharaadhaar.bsnl.co.in/BSNLSKYC/. To get started, they need to enter their pincode, name, and an alternate phone number, and then specify whether the SIM is for themselves, a family member, or someone they know.
