Prepaid card

what are Prepaid Services and their features/advantages

Definition of Prepaid Service:

Prepaid Service (PPS) means that a mobile subscriber can buy a scratch card with a prepaid amount and then increase his account. A call will be accepted or rejected depending on the balance in the subscriber’s account. The call charge will be deducted from the subscriber’s account in real time. In recent years, the global mobile communication service has been developing rapidly, but telecom operators, though satisfied with their service development, are deeply troubled by some inharmonious factors, such as bad debts. The original method of charging mobile phones gives subscribers a chance to escape payments simply by purchasing another SIM card. This behavior resulted in large amounts of bad debts and caused severe losses to the operators. Wireless Intelligent Network (WIN) provides prepaid service as a solution. A subscriber must have enough money in order to make a call, so that the operators no longer need to worry about bad debts.

Features of prepaid services:

  • Call monitoring
    The system will alert the subscriber when his/her balance is not sufficient for specific call duration and the call will be interrupted when the subscriber’s balance is used up.
  • Call barring
    When a PPS subscriber tries to make a call, but his balance is insufficient for specific call duration, the call will not be connected and voice announcement will be played to the caller.
  • Validity period of the mobile phone number (MSISDN)
    The system can set the validity period of the subscriber’s mobile phone number (MSISDN). So, in case the card balance is zero, the MSISDN can still be kept within the validity period. If the subscriber recharges within the validity period, his validity period can be extended depending on the added amount, otherwise the number will permanently be deleted from the system.
