Postal bank card owes SMS fee for two years.

The bank will automatically deduct the SMS fee from the balance of the signed bank card.

1. The bank card that owes the SMS fee is no longer intended to be used. Depends on how much the SMS fee is owed. Under normal circumstances, the bank will automatically deduct the SMS fee from the balance of the signed bank card.

2. If there is no money in the bank and the SMS fee is not enough, the bank will suspend the SMS fee until there is money in the account.

3. Suppose there is no money in the account for a long time, and a certain SMS fee has been accumulated, and the cardholder does not want to pay it back, so he can only use this bank card. If you want to continue to use it, you have to pay back the money you owed before.
