How does China Mobile know who is a member of the home network?

Take Henan Province as an example, it can be handled through business hall, 10086 manual, mobile phone business hall, sending short messages, etc.

1. Open SMS: edit "KTQGQQW" and send it to10086;

2. Add SMS: edit "zjqgqqq+ group code+add number" and send it to10086;

3. Query SMS: edit "CXQGQQW" and send it to 10086.

Due to the different business contents in different provinces, you can call local 10086 for consultation.
