Why doesn't the balance of SMS show the total amount after Guangxi Rural Credit Cooperative turns to regular term?

You can go to the bank outlets to inquire about it.

The SMS notification service of Agricultural Bank of China has been uniformly optimized for all batch transactions, and the balance is no longer displayed (including but not limited to the following contents: automatic contract transfer, overdue deduction, financial return to capital, financial dividend, summary bookkeeping, fund subscription, zero payment, fund redemption, normal repayment, premium deduction and win-win between deposit and loan).

This is because you didn't choose to display the balance when you opened the SMS service. You can inquire and handle it at the bank outlets or through the online banking that has been opened.
