Unicom's mobile phone number should check the balance and traffic. Send a text message to 100 10 to find out what to send. Great gods come to answer.

Because the policies of different cities are different, the SMS instructions sent are different. I suggest you log on to the homepage of Unicom's online business hall, and click convenience service > SMS instruction query to query the instruction code and further obtain relevant information. For example, the short message for inquiring about the balance in Guangdong is as follows, which you can refer to. To query the traffic information, you can try to send 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 contact your local customer service to find out about the inquiry.
