Airtel — Airtel prepaid Sim reactivation

I am using Airtel prepaid Sim for 8 years. I am on an official trip overseas. I did not recharge the Sim for 3 months and it got deactivated. To reactivate I contacted Airtel. I am asked to visit Airtel customer care in person. I cannot travel given the current travel restrictions across all airlines and by the government in the country I work. As this Sim is associated with a lot of my accounts I cannot let this number go.

I was in contact with Airtel through email and I have only 5 days left of the 15 days grace period for reactivation.

Is it possible to hold this number in my name for a fee?

Is it possible to transfer this number to any of my family members?

Please suggest a feasible solution considering my situation that I am overseas.

Thank you
