How long does it take to reissue Unicom's mobile phone card? Who can tell me?

You can use Unicom's mobile phone card after completing the card replacement procedure, and it can be done in about 10 minutes.

If the card needs to be reissued, the user should bring the original ID card of the owner to the nearby Unicom's own business hall for card replacement procedures. After completing the relevant registration and authentication, the staff will bind the number to a new card, and the mobile phone card can be used after the binding is completed.
