Unicom's early warning reminds that high telephone charges are not arrears.

Unicom's early warning reminder of high phone bill refers to the maximum amount that your phone bill can be overdrawn. If the overdraft consumption reaches the credit limit, the payment will be stopped, and the telephone charges for overdraft consumption can be paid in time according to the regulations.

If Unicom prompts that the available line is used up, it may be that your credit line is used up. If you want to continue to use the credit line, you need to pay off the overdrawn phone bill before you can recycle it.
