How to check the phone bill when the Internet of Things card is down?

You can check the amount you owe through the following channels:

1. Log in to the online business hall, and click the phone bill query > account balance;

2. After logging in to the client of Unicom's mobile phone business hall, click Service > Query > Telephone Fee Query > Account Balance;

After entering the page, query date, customer name, available balance, mobile phone number, available balance and frozen balance information will be displayed. If you owe money, your available balance is negative.

In addition, you can also contact the local Unicom manual customer service or go to the local Unicom business hall to inquire about the arrears.
