My mobile phone number is Unicom. What does it mean to check whether the bill is deducted and actually payable in the online business hall?

The total deduction fee is generally for users who have a monthly phone bill refund, such as contract machine or deposit and delivery fee. The phone bill refund directly deducts the phone bill you generated this month.

The actual total amount payable is the phone bill you actually need to pay. This part is generally the phone bill that you actually need to pay after calculating the sum of all appropriations, advance deposits and other refund phone bills and various business expenses.
