Explain that your card may have been used by risky businesses, and such businesses may have issued fake cards. The bank noticed it, so it contacted you actively and suggested that you change your card to ensure the security of your account.

So if you receive a phone call or text message from the bank, you'd better change your card, which is also a kind of protection for yourself.

The new card will be notified by SMS. You can check the delivery of the card according to the mailing number and inquiry method in the short message.

Of course, the new card number and some important card information will change, and you need to activate encryption before you can use it.
