There is no postal savings bank card, and digital RMB is used to receive SMS from postal savings bank.

What you want to ask is: What's the matter with receiving a text message from the Postal Savings Bank in digital RMB without a Postal Savings Bank card? Without a postal savings bank card, you can use digital RMB when you receive a text message from the postal savings bank. Then this message is probably a fraudulent message sent through a pseudo base station. You need to be vigilant and don't believe it easily. You can call the customer service phone of Postal Savings for consultation and confirmation. Investment is risky, please make a careful decision.
