What is Unicom's incoming SMS reminder?

Call reminder means that when your mobile phone is turned off, out of service, busy or dead, all incoming calls will be transferred to the call reminder service platform. When the phone is turned on or returned to normal standby state, the system will automatically send the missed calls to your phone in the form of short messages.

Due to the different policies of different cities, the opening mode of Unicom's call reminder service is also different. It is suggested to contact local customer service 100 10 or go to the business hall to handle it.
