How does Unicom call back to remind you?

Hello, Unicom provides call reminder service. When your mobile phone is turned off, there is no power or signal, the incoming call will be transferred to the incoming call reminding voice platform, and a short message will be sent to remind you of the missed call. Due to the different policies of different cities, the name and charge of the call reminder service are also different. Some of them are called "Call Manager" and others are called "Call Bao". For details of related services, please call the local customer service telephone number 100 10.
