There is less money on the postal savings bank card. I have a bound mobile phone number, but what's the matter with less money and no SMS?

1. The mobile phone number bound by the bank card has not been received, but the balance has changed. There are two possible reasons:

1, check whether the SMS service for balance change is enabled, and the SMS fee is 2-3 yuan per month.

2. The information is delayed or not sent. The main reason is information system failure.

3. The person who steals the bank card balance uses the device to interfere with the mobile phone number reserved by the bank card to receive the short message.

Second, if the money is stolen, corresponding measures should be taken:

1. Change the reserved mobile phone number at the counter of any business outlet of the same trade.

2. Change the card or cancel the account.
