    Re: SIM CARD INFORMATION FROM MOBILE APPPLICATION

    Hi there, bidyut84!

    J2ME has JSR 177 which allows APIs to access the SIM as a smart card.

    The JSR 177 allow extracting the certificate that is on the SIM so you can encrypt/decrypt/sign data.

    Not all manufacturers included a full JSR177 implementation in their phone.

    There are many security-related specs to read and understand in all.

    Commands like changing the SIM PIN code basically require an understanding of the binary protocol itself.
    Simply appending the correct sequence of bytes to an APDU GCF url will get it executed if the JSR177 implementation itself is correct.

    You could have a look at the APDU MIDlet example in the latest Series60 SDK and added documentation in Nokia's Java Developer's Library.

    Using JSR 75 also you can fetch contacts saved on SIM card (along with the contacts saved on phone memory).

    We have seen lot of people having problems reading SIM contacts using JSR-75 on Nokia S60, it allows only phone contacts to be read by this... thou it works on S40 for SIM contacts.

    thanks,
