I have never understood what balances and accounts there are in China Unicom. There are so many nouns and mathematics like this. It is so complicated that it makes me confused.

Hello, it is recommended to use your mobile phone number and mobile phone service password to log in to the China Unicom mobile phone business hall. After clicking "Charge Inquiry" on the homepage, you can intuitively see the detailed items of the mobile phone bill, which should be easier to understand. In addition, you can check the current phone charges by editing text messages 101 to 10010, which is the phone charges incurred from the 1st of the month to the day of bill checking. You can check the phone bill balance by editing text messages 102 to 10010, and you can know how much phone bills are left in the account.
