Will there be SMS notification when the bank card is frozen?

It depends on different situations. Generally speaking, if the user of the bank card opens the SMS reminder function, the bank will notify you by SMS after the bank card is frozen. In addition, if the judicial organs freeze personal bank accounts, they will notify the parties concerned. The bank card is a credit card (debit card), and the reason why it is frozen is probably that the credit card has abnormal transactions, such as malicious cashing, forged information, and continuous password errors.
