Hi

I have tried to install Applet which I made to SIM card.
But It is blocked with the error "Install Applet error: Check Card Cryptogram failed".
I think it seems the keys(S-ENC, C-MAC, DEK) are not matched with SIM card's which i have.
Could you explain how can I know SIM card's keys ?
Should I contact to SIM card manufacturer ?

Thanks
