Sim Card Reader RS-232 error

Hi. First of all I would like to apologize if my question seems stupid. I’m a university student and one of my assignments require me to extract deleted messages from a sim card. I bought a sim card reader online but it keeps giving me this error.

“The system could not be connected to card reader!
Please ensure card reader is connected to RS232 and SIM
card is plugged into card reader correctly.”

This is the sim card reader I bought:

If you have any idea what could be wrong, please let me know. I’ve hit a major dead end and there seems to be no answer for this. Any idea or suggestion is highly appreciated.

Thank you.
