What do you mean by canceling authorization 100 16?

This is within China Unicom, which requires customers to order services such as calling the bell package for weather forecast. Everyone who receives the call should know about these businesses. If you book the service by mistake, please call 100 16 to cancel the service. You can dial 100 10, transfer to the manual desk, ask the operator to inquire about customized services for you, and then unsubscribe from all unnecessary services. As long as there is 100 16 business in the future, don't open it again, it's very dark ~
