What should I do to transfer my mobile phone number to telecommunications?

First of all, you have to see if you have the conditions. If so, you can go to the business hall.

Send the short message "CXXZ# name # ID number" to 10086 by mobile phone first.

Step 2: If it meets the portability requirements, you can reapply for the authorization code.

Edit the short message "SQXZ# name # ID number" with the mobile phone number and send it to 10086.

The third step is to go to the business hall.

After receiving the authorization code, bring your ID card to the business hall and bring the authorization code in.

That's it.
