  1. Hello,
    I have your sim-card and sim-card reader. I want to know that how can I read or set values in the sim-card. In fact, I use Ubuntu 16.04. could you tell me in details.


      1. sorry to bother you again.
        In fact, I am not professional user in Linux.
        in the aforementioned link, it explains about the commands. could you please tell me that how can I open the serial link in Ubuntu?

        Many Thanks.

        1. Hi Eshagh,

          I may misunderstand your question.
          The serial link is shown as /dev/ttyUSB0 (if it is the only serial interface in the Linux machine).
          But you don’t have to manage this: just run the program as per the manual.

          Let’s try to re-explain:
          – down load the source code: clic on “source code”
          say “yes” to “open with archive manager”
          clic on “extract” and put the directory where ever you prefer in your disk
          – open a “terminal”: CRTL+ALT+T shortcut
          – go to the directory: cd – compile, so type: make
          – type: sudo ./program_uicc –help
          will display the options
          – type sudo ./program_uicc –adm

          1. thank you. my problem was ./program_uicc. I did not use “adm”.
            Sorry, My last question is:
            Is there any possibility to change Mobile Country Code(MCC) of the sim-card? I mean the MCC of the sim-card is 208. can I change it to 232 for instance?

          2. Hi,
            yes of course.
            You need only to define the IMSI, that starts by the MCC.
            the other USIM files that are related to the MCC with be automatically computed by “program_uicc”
            the next field in the IMSI is MNC: by default it is 2 digits.
            If you set a 3 digits MNC, you have to specify this (see program_uicc –help)

  2. Hi,
    If HSS has:
    ## HSS options
    OPERATOR_key = “1006020f0a478bf6b699f15c062e42b3”; # OP key matching your database
    and hss-dump-users has:
    imsi | mmeidentity_idmmeidentity | hex(users.key) | sqn | hex(rand) | hex(OPc)
    208920100001106 7 8BAF473F2F8FD09487CCCBD7097C6862 00000000000000000021 33353336363633303332333633313634 E734F8734007D6C5CE7A0508809E7E9C

    Is it correct to set value for the SIM as:
    ./program_uicc –adm –key 8BAF473F2F8FD09487CCCBD7097C6862 –opc 1006020f0a478bf6b699f15c062e42b3

    I’m confused with options –opc and –xx.
