What's wrong with sending a text message to check the traffic fee and not replying to Unicom now?

This may be due to: 1, code error when sending query traffic. 2. Unicom system problems or SMS delays. 3. This number is not used normally, so you can't send SMS. You can check the mobile phone traffic through the following channels: 1, log in to the online business hall and click "phone bill inquiry" > "usage inquiry" > "online inquiry"; 2. after logging in to the mobile phone business hall client, click "service" > "query" > "traffic business query" > "Internet traffic" on the home page; 3.3G and 4G mobile phone users can send short messages CXLL or 107 1 to 100 10 to inquire about traffic usage. Tips: In addition to the above methods, you can also call the local customer service hotline or go directly to your business hall to check the mobile phone traffic.
