Will there be information notice when the bank card is frozen?

There will be relevant information notification. Before freezing the bank card, the bank will send a notice and SMS reminder to the customer, telling the customer that the bank card has been frozen and the customer needs to call the customer service at the bank counter to unfreeze it. The bank card is frozen because the banking system detects abnormal transactions, security risks, violation of bank regulations, etc. The bank will notify the cardholder by SMS, email, telephone, etc.
