Why is there no text message when merchants charge tens of dollars?

What you said is that the short message of the bank card indicates that this short message cannot be received. If you can't receive the SMS, it's probably because you don't have money in your bank card to deduct a SMS reminder fee of two yuan per month. If there is no charge, the system will suspend your SMS reminder service. You can open it again. Or the cell phone has no signal. If the signal is normal, you may receive a message.
