Why do you receive information when you have money on an agricultural bank card?

If the debit card of Agricultural Bank of China is used to handle SMS notification of message service, if the customer's account balance is insufficient or the account is in a special state such as oral loss reporting or password loss reporting, the fee will be deducted for the second time at the end of the month. If the fee is not deducted for three consecutive months, the system will no longer automatically deduct the fee every month and suspend SMS sending. Within 3 months, customers who need to pay through the counter or online banking can open SMS service and only need to pay the monthly usage fee. For more than 3 months, SMS notification can only be activated through counter payment. The specific operation is as follows: (1) Counter: Customer service will open a card at any outlet in the country with my valid ID card and bank card with SMS service; (2) online banking: classic version: customer service > electronic banking channel management > message service > payment > (at present, supplementary payment service is only applicable to KBao customers).
