    Preload application into SIM and installing later on

    Hi,

    I wanted to know is there any possibility to preload an application into SIM card and install it later when we insert this into the mobile.
    Thanks

    Re: Preload application into SIM and installing later on

    Hi,

    No, not really. There are SIM Applications which actually run on the SIM card but they have a very simple restricted interface to the phone functionality (the SIM Application Toolkit).

    There would generally not be enough room (i.e. non-volatile memory) on SIM card to store a decent Symbian application. There is also no "installation from SIM" mechanism defined in the 3gpp specifications as far as I am aware.

    The closest things to what you are suggesting would be either pre-installing to a memory card rather than a SIM card or having the network initiate a download of the application when the phone first registers with a new SIM (probably by sending an SMS with a download link).

    Hope that helps,
    Sorcery

    Re: Preload application into SIM and installing later on

    Thats fine but for this it needs the sim to be loaded with SIM App ToolKit (STK), isn't it? Next it needs the application which I wanted to be installed during insertion of the SIM should be on SIM.

    Does it any limitation of the Symbian OS SWI that it cannot identify the SIS file on SIM and if not is there any procedure to initiate installation of that SIS.
    Thanks

    Are you sure you don't want the application on an MMC/Multi Media card?

    The SIM card can only really be provisioned by the Network operator for applications and these are limited to 4K or 16K I think.

    Also as Mark pointed out you would still need an application to boostrap your application from the SIM card and launch the installer as there is no provision in any firmware for it. The SIM card acts like a mini OS in that it provides and API (SAT) that you can use to talk to the card but not mutch over than. The SAT is restricted and only avaliable to Symbian licencees.

    Access to the SIM card contents is tightly controlled because for example it includes encryption keys for the phone.

    I suggest you read up more on SIM cards
