How to communicate with the SIM card in the external SIM card slot of the surface pro9 device?

junzilan 0 Reputation points

I want to use the surface pro9 device to access the SIM card in the external SIM card slot. After inserting the card, the device can log in to the 5G network.

In my application, I can list Microsoft UICC ISO card readers. Resetting can return the correct ATR information for this SIM card.

When I want to transfer the apdu command: 00a40004023f00 to the card. Functional interface: 'SCardTransmit' returned error code 0x57

Is there any way to send commands to the card?

    Hi, @junzilan.
    Welcome to Microsoft Q&A!

    Please set the type LONG of return value for SCardTransmit. If anything wrong, it will return the value from this list.

    In order to send commands to the card, you can refer to windows-classic-samples.
    If you want to test it, you might need to add the Winscard.lib for APIs (SCardTransmit, SCardEstablishContext, etc.) and initialize the pointer.

    You're so kind of providing a reproducible minimal sample.

    Thank you.
