Why does the bank card information bound to the mobile phone receive the same information twice?

1. It may be a network communication failure, and the operator repeatedly sent a text message.

2. It may be repeated deduction. Please log on to the online banking immediately or call the hotline on the back of the bank card to see if there is any repeated deduction.

3. When the Postal Savings Bank repeatedly sends yesterday's transaction information, first call the customer service to check whether this consumption is double-booked.

4. Secondly, if it is not, it is a communication problem of the system, and short messages are sent repeatedly.

5. Finally, someone will pretend to be a fraudulent short message sent by the bank.
