How long will Unicom be notified of arrears?

1. Our company will send SMS reminders to post-paid users who have not paid the phone bill of last month in installments from 20th to 24th every month to remind them to pay.

2. When the prepaid user's "pre-deposit balance+available funds for the current month+available prepayments for the current month+credit-historical arrears-real-time telephone charges" is less than the dunning amount, the system will call out circularly to remind the user to pay the fee through the voice mode of1kloc-0/.

Tips: Take Chongqing as an example. Different provinces may have different policies. For details, please consult the customer service hotline of the place of origin.
