When I open the message, how can I tell whether the message is sent to card 1 or card 2?

Take the red rice note2 mobile phone as an example. The specific method is as follows:

1. Find the information icon on the phone desktop and click Enter.

2. Find the corresponding information. The upper right corner of the general information will be marked with 1 or 2, representing card 1 or card 2 respectively.

3. Open the corresponding information, and 1 or 2 will be displayed in the upper left corner of each information to see if it is card 1 or card 2.
