What's the matter with Unicom's traffic query and texting?

Unicom provides a variety of ways to query the remaining traffic. You can send a short message "CXZLL" to 100 10 to make an inquiry, or you can make an inquiry through the net hall and Unicom APP. Take China Unicom APP as an example:

Enter the mobile phone number and password, login-service-query-balance query, and you can query the remaining traffic and minutes of the mobile phone card.
