How long SIM card will be active, if we won't recharge and having main balance along with disabling the auto debit option.
I have written to Airtel Customer Care and got a response in writing (Email).
Airtel continues to maintain TRAI Guidelines. Hence, if you do not recharge, and disable auto-debit option, then the following occurs:
1) If no chargeable activity or recharge is observed for a continuous period of 90 days, an amount of Rs 20 will be deducted from main balance, and validity will be extended by 30 days. This will continue until such time the balance falls below Rs 20.
2) If your balance is below Rs 20 and there has been no chargeable activity or recharge for a continuous period of 90 days, the number will be permanently deactivated. Telcos usually send warning SMS texts before taking such a stern step.
3) Even if the number is permanently deactivated, TRAI Guidelines provide options to claim it within a stipulated grace period.
Note:
Chargeable Activity is defined as any activity that deducts an amount from your balance (main / promo balance)
Recharge is defined as any valid recharge for that particular telco and circle.

1) No Prepaid mobile connection shall be deactivated on account of non-usage for a minimum period of 90 days.
2) Non-usage means absence of any incoming or outgoing call or outgoing SMS or data session or usage or value added services or payment of rental.
3) Beyond 90 days, an amount not exceeding Rs 20 shall be deducted from the Pre-paid account, if balance is available, for extension of the period of non-usage by 30 days at a time.

A subscriber whose connection is deactivated shall be given a minimum grace period of 15 days within which he can reactivate the same number by paying an amount not exceeding Rs.20.
