Dear friendsI have a bsnl 3G prepaid connection in kerala. The main account is valid till 28-2-2011. I want to recharge with Rs 4200for the 6 month unlimited 3G plan.Do i need to recharge my main account to increase the validity or will this 4200 recharge increase my main account validity or are they seperate accounts?I dont want to lose the 3G usage once my main account expires.Also is it safe to do the 4200 recharge through their portal?any help is appreciatedthank youregards
