How to use Unicom mobile phone number to send SMS to check traffic?

If you need to use SMS to query traffic usage, you can try to send CXLL to 100 10 for query. If you can't find out, I suggest you use this number to log in to the online business hall, and click "phone bill inquiry" > "usage inquiry" > "Internet traffic" on the home page to find out the usage and remaining situation of mobile Internet traffic in the current month. You can also contact Unicom's manual customer service for inquiry.
