1. No service: If the SMS reminder service is not enabled when handling the bank card, you will not receive the SMS notification of the relevant fees. This requires users to actively choose to open services when handling bank cards or subsequent operations.

2. Insufficient bank card balance: When the bank card balance is insufficient, the bank will send a short message to remind users to deposit in time. If the account balance continues to fall below a certain threshold, the SMS reminder service will automatically stop. Ensure that the account has enough funds to ensure normal use and receive SMS notifications.

3. SMS is intercepted: Sometimes the SMS sent by the bank is mistaken for spam by the mobile phone security software and intercepted. Check the mobile phone settings and security software, add relevant numbers to the white list, and ensure the normal reception of SMS notifications sent by Jilin Rural Credit Cooperative.
