How does China Mobile transfer to China Unicom to handle the port number transfer service?

If you need to handle the number portability service, you can do it through the following steps: 1. Qualification inquiry: You can send a short message "CXXZ# user name # ID number" to the home operator to inquire about the number carrying qualification (mobile 10086, China Unicom100, telecom 100066). 2. Fill in the application: those who meet the requirements of port number transfer can enter the China Unicom mobile phone business hall APP, click "Services" to handle "Port Number Access", fill in the application information, wait for the staff to contact, deliver the goods to the door and assist in port number transfer and new card activation. Tips: There may be differences in policies among provinces and cities, and the attribution policy shall prevail.
