Business conversion means that the three business services ordered in the package (including the business services given in the package) can only be freely converted with each other in the current month according to the conversion rules, and business services such as discount superposition outside the package and other activities such as gift or recharge (such as traffic card recharge traffic) are not within the conversion scope. For example, the remaining voice service can be converted into traffic according to the conversion rules. The conversion rule is 1 min voice =2MB traffic =2 SMS/MMS. The upper limit of voice that can be used for conversion is 1000 minutes (sum, that is, the total duration of voice conversion for multiple times does not exceed 1000 minutes), the upper limit of traffic that can be used for conversion is 1000MB (sum), and the upper limit of short/multimedia messages that can be used for conversion is 100 (sum).
