Essential Services PPS & MVPN

Prepaid Service (PPS) means that a cellular telephone subscriber can raise his account balance by purchasing a scratch card with a prepaid sum. A call will be taken or rejected based on the balance in the subscriber’s account. The call fee will be deducted from the subscriber’ account in real time. Telecom operators are satisfied with their service development, but they are profoundly troubled by some inharmonious aspects of their service development, which includes bad debts. Subscribers are given an opportunity to escape payments by simply buying another SIM instead of recharging the old SIM. This behavior caused serious losses to the mobile operators and resulted in considerable amounts of bad debts. Wireless Intelligent Network (WIN) supplies prepaid service as a remedy. A subscriber must have enough cash to be able to make a call, so the operators no longer need to worry about bad debts.

At Present, Max Mobil has around 100,000 subscribers, with more prepaid than postpaid subscribers.

Edges of MVPN

Mobile Virtual Private Network (MVPN) provides cellular subscribers with private network services similar to the great expense if a business mainly uses mobile phones. If there is a MVPN created not only the mobile phones will be economically to use but the call costs may also be controlled. Therefore, it’s an excellent option for large businesses to set up MVPN in offices situated between distinct cities and within the exact same city. Since it’s hard to handle distinct telephone numbers of various sections, MVPN helps businesses to allocate amounts in a manner that is suitable for each section. Compared with rented or branch exchange, MVPN recognized by WIN can make complete use of the public network facilities. For the telecom operators, MVPN can efficiently bring subscriber groups, and quickly raise the distribution amount since MVPN subscribers are generally companies with frequent calls and call traffic.

The operator can be empowered by mVPN with competitive advantages over its rivals.
