What does port number transfer mean?

The scientific name of "number portability" is "number portability" (NP), which means the number portability of mobile phone users. "Number portability" refers to the service that cellular mobile phone users change their contracted basic telecommunication service operators, while the user number remains unchanged in the same local network.

To handle the number portability business, we must first inquire whether the number meets the portability conditions. Users who meet the carrying conditions apply to the carrier for the carrying authorization code, and apply for carrying in the business hall of the carrier. Upon completion, the portability party will provide you with a new mobile phone card. The specific process is as follows:

1. Inquire whether the carrying conditions are met: edit the short message "CXXZ# name # ID number" and send it to the customer service number of the carrier to find out whether the carrying conditions are met;

2. Obtain the authorization code: edit the short message "SQXZ# name # ID number" to the operator's customer service number;

3. Import: After obtaining the authorization code, the importer's sales staff will apply for import and open a new card for you in the system.
