The reliability of text messages needs to be screened by yourself.

The SMS notification template for a blocked credit card is as follows:

"Your credit card with the last number xxxx has been suspended by our bank's credit card center due to xxxx reasons."

If other suspicious words appear, you need to be more vigilant.

The reasons why a credit card is blocked are as follows:

1. The credit card is overdue for more than three times. When the overdue amount reaches the limit, the bank will suspend the card.

2. If you illegally cash out or maintain a card, the bank will reduce the credit card limit or suspend the use of the credit card.

3. When the bank believes that a certain credit card is at risk, it will suspend the credit card for safety reasons.
