How does Unicom query how many services have been opened by SMS?

You can try to edit the short message "YDYWCX" and send it to 100 10. You can query the value-added service by replying to the corresponding code according to the SMS menu prompt. In addition to the above methods, you can also query the opened value-added services in the following ways: 1. Log in to the online business hall/click to handle business > handle records > all records; 2. Log in to the mobile phone business hall, and click Service > Query > Business Query > Business Acceptance Record to query the SP business information you handled, such as the acceptance date. 3. Contact the local manual customer service or inquire in the local business hall.
