Sometime we need to disable a javacard applet inside the SIMCard without remove it.
Once disabled, later we may want to activate it again. Global Platform spec define
a way to do this.
Let say we have javacard application with AID A00000001840840000, to lock it simply
this command through GSM 03.48 envelope command to SIMcard:
80F0408309A00000001840840000
Meanwhile, once locked/disabled, simply send this GP command to enable it:
80F0400309A00000001840840000
Detail:
0x80: CLA
0xF0: INS for SET STATUS command
0x40: To indicate that this is a javacard applet application
0x83: Set to locked meanwhile 0x03: set to unlocked (state: SELECTABLE)
0x09: Length of AID to disabled/enabled is 9 bytes
A00000001840840000: this is the AID of applet
