How can Unicom use SMS to query what services have been opened?

Hainan Unicom launched one-click query unsubscribe service for mobile network value-added services. Users can edit the short message "0000" and send it to 100 10 to quickly inquire about the value-added services handled by their own numbers. According to the reply result, edit "T# value-added service serial number" to 100 10 again to unsubscribe from the specified service. Due to different policies in different provinces, please consult the local Unicom customer service hotline for details.
