Introduction of call reminder function

If you use a vivo mobile phone, the incoming call reminder function means that all incoming calls within 24 hours will be saved for you through the incoming call reminder platform when your mobile phone is turned off, out of service area, offline or the signal is not good. After the mobile phone returns to normal, all incoming calls will be sent to your mobile phone in the form of short messages. To enable this feature, you need to apply to the operator. Please consult the operator's customer service for specific charges.

The telephone numbers of the four major domestic operators are: 10099 (China Radio and Television), 10086 (China Mobile),10 (China Unicom) and 1000 (China Telecom).
