Try to approach the Jio SIM authroized seller nearby.

Let them know about your old Jio mobile number

They will give free SIM replacement

You have to charge extra amount for its 'activation' and you have to charge it again on different 'tariff' like monthly or quarterly plan too.

That's it. They have your personal detail when you first time bought it so, nothing to submit any document for it.

You can contact the customer care services which will guide you in the matter.

Generally the plans are valid for a particular period and after that you can not use the SIM as you do not have valid talk time and data with you.

Alternatively, you can simply go to a dealer for recharging it for a minimum configuration plan say Rs 99 for a month. As soon as you top up, it may get activated by default. After that you can go for better plans like Rs 450 which gives you 1.5GB data per day and free calls and SMS for 84 days. These plans change time to time so you please check the recent tariff applicable and plans available from the nearby dealer.
