Why didn't you send a text message after the bank card reserved the mobile phone number?

1. Your bank card doesn't have SMS reminder function. Generally, you need SMS reminder function to receive SMS reminder of account balance change.

2. The reminder amount set by SMS reminder function is too large. In this case, transactions below the reminder amount will not be reminded by SMS.

3. It may be some special transactions, such as batch payment, and the SMS may not be received or delayed.

4. There is a problem with the line of the mobile phone number, which can be solved by resetting the line of the calling mobile phone customer.

5, mobile phone problem, try another mobile phone.
