Does port number transfer affect bank cards?

The port number transfer will not affect the bank card.

1. The mobile phone number of the bank card is bound only for real-name authentication. As long as this number is used in my name, changing operators will not have any impact on the bank card I am bound to.

2. It is best to know the relevant policies in advance before port number transfer, and then handle the network transfer business according to the SMS reminder of the operator, and know in advance whether port number transfer will affect the use of mobile phone numbers. For example, Unicom's services, points, phone bills, VIP, etc., will be invalid after they are taken out. Even if it is brought in again, it is equivalent to recalculation by new users. Unicom's SP or value-added services can't be used after they are taken out. The service offered by a third party depends on the situation of the other party's system. You can consult a third-party service provider.

3. If you still have questions in this respect, you can consult and confirm with the bank and the communication operator respectively before handling the port number transfer, and then decide whether to transfer the port number to the network after knowing the relevant situation in detail.

: 1. Bank cards are generally divided into credit cards and debit cards. Debit cards here can be divided into transfer cards, special cards and stored value cards according to different functions. The transfer card can transfer money, deposit and withdraw cash and spend money. A Special card is a debit card that is used in a specific area and has a specific purpose (except for department stores, restaurants and entertainment industries), and has the functions of transferring money and depositing and withdrawing cash. Stored value card is a prepaid wallet debit card in which the bank transfers funds to the card for storage according to the cardholder's requirements, and directly deducts money from the card during the transaction. Debit card can't be overdrawn, and it has the service functions of cash deposit and withdrawal, transfer and remittance, credit card consumption, collection and payment, asset management and so on.

2. Credit cards have the function of overdraft, and different users get different credit lines when applying. In addition to the function of overdraft, the credit card itself also contains other rights and interests when used, for example, you can enjoy certain discounts when buying goods, and credit card consumption will also generate points when shopping. However, after daily use of credit cards, we must pay attention to repayment on time and not overdue. Because there will be penalty interest after overdue repayment, the longer the time, the more penalty interest will be generated. Moreover, overdue repayment will affect personal credit information and have a bad influence on individuals. After the credit information becomes worse, it will affect the handling of subsequent loans, such as car loans or mortgages.
