Right. I use Tata BB Postpaid connection. the difference between a postpaid connection and a prepaid one, is that you get a bill in the beginning of the month for the current month (in the case of postpaid) and that you buy a prepaid card(not sure exactly, could any user please clarify this?) and charge your account (in the case of a prepaid account).i.e., in both the cases you end up paying BEFORE you use your BB.So WHY do they call it POSTpaid and PREpaid?
