Unicom's mobile phone is in arrears What number can I dial to find out how much phone bill I owe?

If you need to inquire about the arrears, you can log on to the homepage of the online business hall www. 100 10.com, and click phone bill inquiry > account balance to inquire about account balance, customer name, available balance, mobile phone number and frozen balance information. If you owe money, your available balance is negative.
