How do I send a text message to China Unicom to inquire about value-added services? Thank you, can you help me?

How to check the value-added services activated by a number:

1. Log in to the online business hall/homepage and click on Call Charge Inquiry>Other Inquiries>Business Processing Records;

2 .Log in to the mobile business hall client, click Service>Query>Usage Query>Business Acceptance Record;

3. Send the editable text message "YDYWCX" to 10010, and reply with the corresponding code according to the text message menu prompts ;

In addition to the above methods, you can also consult the local customer service or business office for enquiries.
