There may be four reasons.

Specific reasons: 1. The phone number is incorrect. It is possible that the previous owner of the phone number you are using now handled certain business at Agricultural Bank of China, such as loans, investments, etc.

2. Call to verify whether it is me who swiped the card. The bank has a risk control system that can monitor abnormal information about cardholders and conduct risk warnings to prevent risk events.

3. Make phone calls to promote credit card installment business. After we swipe our card, we will receive installment prompts via SMS and WeChat. If we do not follow the prompts to carry out installment operations, the bank will call us to recommend installments, especially before and after the bill date.

4. Encourage bank card fraud knowledge.
