Top Previous Next

Descriptions

This feature allows the prepaid customer to transfer all or part of his account balance to other prepaid account. After a successful transfer, a notification short message will be sent to both the transmitter and receiver. The expiry date of transmitter won't change after transfer. For the expiry date of receiver, divided into the following two conditions:

•If the expiry date of receiver is longer than the transmitter's, leave it as unchanged.

•If the expiry date of receiver is shorter than the transmitter's, replace it with the expiry date of transmitter.

There are three ways to transfer balance from one prepaid account to another:

| Balance Transfer by Dialing Service Number

Subscriber may dial the toll-free Balance Transfer service number to transfer his account balance to another account by following the IVR instructions.

| Balance Transfer by Short Message

Subscriber may edit a short message in an appropriate format (<Receiver Number>#<Credit>) and send it to the Balance Transfer service number.

Please note that the balance transfer by short message service is dependent on the reliability of Short Message Service Center (SMSC), and it doesn't initiate real-time session between customer and system. For the security reason, the balance transfer by short message service is not recommended.

| Balance Transfer by USSD

Subscriber may dial the USSD service number to activate transfer balance service. Follow the prompt to enter string in an appropriate format (<Receiver Number>#<Credit>). •The <Receiver Number> is the whole number with CC and NDC. •The <Credit> is in the same currency format as balance inquiry. Use asterisk as the decimal point and ignore the 0 at the end.
