Every time I enter the Unicom business hall to inquire about the bill, there will be a short message reminding me how long it will take to inquire. How can I cancel this message?

Because the call list involves your privacy, the system will automatically send a reminder every time you inquire, so as to prevent someone from knowing your service password to inquire about your call record. If you don't do it yourself, you can also change your service password as soon as possible. This message cannot be cancelled.
