P-L496G-CELL02 use the plastic SIM

[harold_f]

Hi, we struggle to get P-L496G-CELL02 up and running with a plastic SIM. I know that set pin Sim_select0 to LOW to select the plastic SIM. However, I don't know what software to use and how to set it up. I am a beginner in embedded development. In addition, I want to learn how to interact with AT instructions.
