I don't have postal savings card, but I got a message.

The reasons why no bank card receives SMS are as follows:

1. Error message: Sometimes, the banking system or a third-party institution may send the wrong short message, which may be caused by input error, system failure and other reasons.

2. Fraudulent information: Sometimes criminals send fraudulent short messages in the name of banks to induce users to click on links or reply to short messages, thus stealing personal information or funds.

3. Marketing information: Sometimes, banks will send marketing information to potential customers to promote their products or services.
