How does Unicom inquire about value-added services through 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.
