My mobile phone card is mobile. I want to change it to Unicom. How to change it?

number portability, which is also called number portability, means that a user of a mobile telecom operator can become a user of another operator without changing his mobile phone number and enjoy various services provided by it. The specific application process is as follows:

Step 1: First, the customer needs to edit "CXXZ# user name # ID number" and send it to the customer service port of the operator where the number originally belongs to check whether it meets the transfer conditions;

example: a mobile customer brings out a query, edits "CXXZ# username # ID number" and sends it to 186.

case 1. inform of non-conformity: the content of the short message received by the user will inform the reason of non-conformity, and if it involves the termination of the contract or the unbinding of the number, the user can be guided to apply for it in the mobile business hall.

in case 2, the user must send a short message again to obtain the portability authorization code.

step 2, edit the "SQXZ# user name # certificate number" after the query meets the requirements, and send it to the customer service port of the home operator to initiate the application for portability and obtain the portability authorization code.

example: the mobile customer takes out the authorization code to obtain it, edits "SQXZ# username # ID number" and sends it to 186.

step 3: handle the transfer service in the owner's business hall with the authorization code;

For example, if a mobile customer wants to bring in Unicom, he/she will go to the business hall of Unicom to handle the transfer business.

Tips: Please use "#" in English when editing the "#" in the text message.
