I have Netconnect plus with over 13 GB balance.The current balance validity is till March 2012. I had last recharged it for 18 GB @ Rs 3000/- with 6 months validity.I would like to know if I can recharge with say Rs 250 every month to keep using the 13 GB balance after the current validity period expires. If I recharge before expiry, will the balance 11 or 12 GB at that stage be available to me or will it lapse?
