How does Unicom close the missed call reminder? Ask good people to answer ~

If you mean the missed call number reminder SMS service, it is generally Unicom's secretary desk service (the business name may be slightly different in different regions). You can call Unicom customer service and turn to the manual desk to cancel the business and consult the operation method of canceling the business. Call forwarding needs to be reset. If you don't want to cancel the service, you need to cancel the reminder information temporarily. You can cancel all call forwarding status in the phone settings, and then set call forwarding if necessary. (Cancel All will close the reminder message of the missed call number. )
