How does China Unicom cancel the primary and secondary cards?

Unicom users who need to untie the secondary card can go to our own business hall with the original valid ID card.

Tips:

1. If the main card and the auxiliary card with different account names want to dissolve the relationship between the main card and the auxiliary card, both parties must go to the site in person with valid identity documents.

2. The user number must be in a normal state to handle the unbundling business of the secondary card, and it cannot be handled when it is in an emergency stop (loss reporting), stop to ensure the number, and stop due to arrears.
