How does Unicom send a text message to check the phone bill and traffic fee?

If you need to query the phone bill balance by SMS, you can edit the SMS "CXYE" or "YE" to 100 10 to query the current available balance fee; If you need to use SMS to query traffic, you can edit the message CXLL (case-insensitive) or 107 1 to 100 10 to query the traffic usage of this month as of the previous day. You can also call Unicom's customer service hotline 100 10, and make inquiries according to the voice prompts.
