Why can't Unicom send SMS to unsubscribe from traffic?

Unicom cannot unsubscribe from traffic packets for the following reasons: 1. This number does not open traffic packets; 2. The service does not support online self-service channels such as online business hall and mobile phone business hall, and can be cancelled by other means; 3. The unsubscribe instruction or path is incorrect, so it is impossible to unsubscribe. The above guidelines still cannot be solved, so you can contact the local manual customer service for feedback.
