How does China Mobile unsubscribe from the family number?

Are you talking about canceling the membership of the home network? Due to the different business regulations in different provinces, taking Henan as an example, the SMS cancellation method is as follows:

Delete member: edit "scqgqqq+ group code+delete number" and send it to 10086 (the remaining minor numbers cannot be deleted when the major number deletes the minor number).

Sign out voluntarily: edit "tcqgqqq+ group code" and send it to 10086.

Cancel business: edit "qxqgqqq+ group code" and send it to 10086.
