today visited local CSC for inquiring to any validity recharge as my mobile sim showing 1 week remaining .
auntie asked " u have to tell me as there are so many recharges "
I - " can u show me whom if I ask as that desk board regarding 3G is not showing such things .
auntie - ummmmm , I don't know , why not visit that other CSC ( about 6 km from here )
after checking :: BSNL 3G :: Prepaid
I still no idea which 1 should I got for validity extend , any 1 ?
