BSNL Prepaid EVDO Recharge is very easy. Today I have recharged it by 110/- for six months validity from paytm online recharge site. I have chosen STV for 110/- recharge. There are two options Topup and STV for BSNL recharge. Also I have recharged 350/- as Topup for balance. My plan is 750Unlimited so I am maintaining my balance above 750/-. The plan charge 750/- will be automatically deduct on 16/02/2012 from my main balance.
