What is the business content if I am reminded of missing words?

"Missed call reminder" service is a short message reminder service provided by China Telecom for Tianyi mobile phone users who have not opened personal communication assistant service. When the user is turned off, out of service area, missed the phone or the phone is busy, missed the incoming call, the system automatically sends a short message to remind the user of the incoming call information. From April 20 1 year 12, it is applicable to China Telecom Tianyi mobile phone users who have not opened the personal communication assistant service (the personal communication assistant has included the function of reminding missing messages). Users who have opened the function of reminding missing messages can receive reminder messages when roaming outside. Only 2 yuan is needed every month. When the user number receives a missed call reminder message, it will not charge any fees, and the call back will be charged according to the basic phone bill standard. It can be handled through SMS business hall, handheld business hall, online business hall, 10000 and business hall. When the missed call reminds the user that there is a missed call because he can't answer the phone normally, the system will automatically give a voice prompt to the caller, which can be divided into three types according to the status of the missed call (that is, unable to connect, busy and power off).
