1. Whether the credit card will receive SMS due to risk control depends on the specific situation. If it is serious, you will receive a related short message, the content is roughly as follows: Dear customer, your credit card has a risky transaction in line X recently, so I would like to remind you to standardize the use of the card. Banks will take measures such as reducing the credit card quota in accordance with regulatory requirements to ensure the security of credit cards. If the circumstances are not serious, you can not send text messages, but the amount in the card will be reduced.

2. The most common phenomenon that credit cards are controlled by the wind is that cardholders illegally cash out or maliciously overdraw. Once some banks suspect that your credit card is cashed out, they will directly seal the card without warning and reduce the limit.

3. If the credit card is controlled by the wind, you must prove to the bank that you are using the card normally, and you can submit relevant evidence. If it really violates the rules, there is no way to solve it by being controlled by the wind. You can only keep a good credit card habit in the back and gradually gain the trust of the bank.
