Answer 1

It seems that info might be in an Intent extra with the key "simSlot".

public void onReceive(Context context, Intent intent) {
    ...        
    int simSlot = intent.getIntExtra("simSlot", -1);
    ...
}

I couldn't find any info on this, either, in my admittedly brief search, so I'm not sure how universal this is, or in which Android version this might have been introduced. I found it by dumping all the extras on the delivered Intent in a Receiver on my device.

Didn't work for me in android 10. Always getting simSlot -1 on receiving SMS in both SIM cards – Dara

@WijaySharma That doesn't surprise me. This should've been a comment, rather than an answer. Sorry that it mislead you. If I get some time later, I'll do some research, and update this answer. I'll let you know if/when I do. – Evy

This work for Lenovo phones with Mediatek chipsets

public void onReceive(Context context, Intent intent) {
    ...        
    int simId = intent.getIntExtra("simId", -1);
    ...
}
