Can I change my mobile phone card into Unicom card?

Mobile users can change their numbers and cards to Unicom users. You can edit the short message "SQXZ# customer name # ID number" and send it to the mobile company's customer service number 10086 to obtain the authorization code, and then go to Unicom's business hall for transfer. As the authorization code is valid within 60 minutes, it is recommended that you send a short message when you arrive at Unicom's business hall.

If you don't receive the authorization code, you need to contact customer service 10086 to find out if there are any restricted services, and then cancel the related services before starting.
