To convert your BSNL prepaid connection to a postpaid connection while retaining the same number, visit a nearby BSNL Customer Service Center. You'll need to fill out a application form and provide the required documentation, including identity proof and address proof. Once your request is processed, you will receive a new postpaid SIM. The transition usually entails a few formalities but typically takes a short time to complete.
