The bank card has no money. Is the SMS charge still deducted by 2 yuan?

If you don't have money, you won't continue to deduct the SMS fee, but if you have money inside, you may make up the SMS fee that you couldn't pay before.

If you don't need the SMS prompt, you can cancel it. Now the mobile banking APP opens the notification, as long as the bank card has a transaction, the user will be notified, and you can see the transaction record of the information, which is more convenient and private than SMS. If you don't use a bank card, you can cancel it, otherwise you will eventually sleep.
