I am trying to authenticate to a SIM Card and I have all the necessary keys. But when I try to authenticate to the SIM Card, I get
the error
<< 6D 00
<< Invalid instruction

Could anyone explain to me why this happened?

sw=0x6D00 means INS not supported. That is to say your card does NOT support authentication command. Maybe your card is not compliant with the specifications. NOTE that not all cards support mutual authentication.
