The first time the card is inserted in the card reader, Card Admin will not recognize the Card ID (the ATR signature from the card), so you'll need to select the ID and a correct predefined Card Type.
If you accidentally chose the wrong card type, please look a this article on how to change it.

In order to view and edit files on the SIM card you'll need to verify the secret codes. Best practice is to verify them all at once before you start browsing the card and open files. The secret codes for this particular card can be found here.
The CHV / PIN or ADM secret codes are often required to use a command on a file (for example, Read, Update). The secret code to be verified for a given command is specified as an access condition when the file is first created.
To verify a secret code:
Note: If you have checked this box, enter the value carefully as an incorrect value will decrement the ratification counter of the secret code.
6. Enter the code value in the Secret Codes box and click Verify. The result and the corresponding status words are displayed in the status bar below.
For all cards, if you specify an incorrect value for the secret code, the Counter (ratification counter (Counter assigned to each CHV and ADM code in the card. It records the number of consecutive times the code has been incorrectly entered. If the ratification counter reaches 0 after a pre-determined number of attempts (chosen when the secret code is first created), the secret code is "blocked". If the secret code is entered correctly before it is blocked, the ratification counter is reset to its initial value, otherwise it must be unblocked using the Unblock CHV command. The purpose of the ratification counter is to prevent exhaustive secret code attacks.)) is decremented. If the Counter reaches 0, the card is blocked. In this case, select the Unblock tab.
As these cards are non-gemalto cards, and as the commands to verify Admin codes are different between different suppliers of SIM cards, we'll need to verify ADM codes by sending a specific APDU command.
Make sure you got SW1=90 SW2=00 response from the exchange. (Success)
That's it. You have now succesfully verified the ADM code and you can proceed with editing files (EF's).
On the Smartjac 2G cards the authentication key is stored under MF / EF_220C
The Card Admin scans some predefined ranges and for that reason some files can not be seen unless you specifically select them.
Enter the value of the Ki you want to use. The Ki is 16 bytes and the 2 last bytes are the CRC checksum.
How to calculate this checksum is explained in the Appendix here.
In the case of Ki being 000102030405060708090A0B0C0D0E0F the checksum is 513D

Each mobile belongs to one out of ten randomly allocated mobile populations, defined as Access Classes 0 to 9. Moreover, some mobiles may be members of one or more out of 5 special categories (Access Classes 11 to 15). Both these access classes are stored in the SIM.
If the mobile belongs to at least one access class allowed by the network, it can make calls. Otherwise all access attempts will be barred. So you need to set a value in this file. If you don't know, just set 00 01 (Normal priority level 0 allocated)
6F 78h, Access Control Class, is a transparent file containing the mobile’s random access class and possibly a special access class.
Enter MCC, MNC and Subscriber number and click "Update" button.
