how to use verify pin command.

i tried "00 20 00 01 08 12 34 ff ff ff ff ff ff" to verify mf pin with airtel sim. i got response "69 84 Command not allowed". i am using a sim card reader & pcsc-lite-1.7.4 library.
When i use " 00 20 00 01" it returns count as 3.
"Received: 63 C3"
(1234 is the pin for airtel & it works in mobile)

ref. 102.221 & 31.102
