Is the mobile phone number of the main card informed by SMS or reserved for the mobile phone number of the secondary card?

The consumption of the secondary card is a short message prompting the mobile phone number of the main card.

Whether the credit card is consumed by the main card or the sub-card, the main card will know the consumption situation, and the main card can inquire about the details, and there are even SMS reminders to inform consumers, as well as regular statements.

1. The main cardholder of a credit card can apply for supplementary cards for immediate family members (parents, spouses or children). Domestic applicants must be 14 years old, and overseas applicants must be 18 years old. You can hold your own primary card and someone else's secondary card at the same time.

2. The secondary card must be of the same type as the primary card and enjoy the same credit line with the primary card. Without an independent account, you can't log in to online banking independently, and the repayment is included in the main card account.

3. The rights and obligations of the supplementary card are basically the same as those of the main card, and the supplementary card can enjoy the same preferential annual fee policy as the main card. For example, if the main card is swiped six times, the annual fee of the main card can be reduced.

4. After the secondary card is issued, it will be sent according to the address of the main cardholder. Make sure that the address of the main cardholder is valid before issuing the card.

You can also reserve your personal mobile phone number, and the text message will be sent to your mobile phone number.

Extended data:

After using the credit card, the bank will send a text message to remind the cardholder to know the consumption of the credit card in time.

However, this kind of short message may also be charged, usually deducted from the credit card on a monthly basis. Many cardholders think that they don't have to pay back if they don't spend that month, and the result is overdue. Of course, there are also free gifts from banks.

Although some banks charge for SMS notification of credit cards, if the credit card is stolen, the cardholder can report the loss immediately to reduce the loss, so SMS notification of credit cards is still necessary.
