METHOD FOR PROVIDING ALTERNATE PREPAID BILLING SERVICE

摘要

The present invention provides a method for providing alternate billing service to a user whose service is provided on a prepaid basis. The prepaid service includes a first billing source to pay for the service. An alternate billing source is also provided. The alternate billing source, which is different from the first billing source, is used upon the existence of a predetermined condition. Examples of predetermined conditions include the account balance of the first billing source dropping to zero, communications with predetermined telephone numbers, the user being in a predetermined geographic area, the time of day, or the day of the week.
