Why can't I receive the verification code of the secondary number?

Because the secondary card is also an independent card.

The primary and secondary cards are only for packages and fees, and they are used independently. The primary card can't view the messages sent and received by the secondary card.

On the basis of the main card, the secondary card provides customers with both the main card and the secondary card. The main and auxiliary cards realize combined payment, and the main card is used as the payment account.
