How does Dalian Unicom inquire about telephone charges and traffic through SMS?

If you need to check the phone bill balance by SMS, you can send "CXYE" or "YE" to 100 10. If you need to check the mobile Internet traffic by SMS, you can send CXLL (case insensitive) or 107 1 to 100 10 to check the traffic usage of this month as of the previous day.
