Answer Question

1 Answer - Sort by: Date | Rating

    It is used to make calls through a cell phone. The very term prepaid means already paid, it has a certain amount of balance which can be recharged via a prepaid refill. The amount in the prepaid SIM card is reduced when you make a call through it. Unlike the post paid SIM card where the subscriber has to pay the outstanding bills after making all the calls, in prepaid the subscriber is charged instantly through the card.

    SIM card stands for 'Subscriber Identity Module'. It is a very small 'Smart Card' which is the size of a small postage stamp. A SIM card can store certain details like Telephone numbers, certain preferences, subscription information and text messages (SMS).
