I was wondering if anyone knows a Android RIL implementation (and platform) that does use something other than CRSM (like CSIM, or some other type of raw SIM access).
AT CSIM Command: This one is the eldest and most well-known command: some phones allow you to use one of the standard-defined-but-not-always-implemented AT command AT CSIM which let’s you to send raw APDUs (=”commands”) to the SIM-card via the modem.
If you have any better or further insight, please let us know ASAP!

However the TE should be aware of the precedence of the GSM application commands to the TE commands. ME handles internally all SIM-ME interface locking and file selection routines.
Parameters: - on a successful completion of the command previously issued it gives the requested data (hexadecimal character format).
We can't use STK because we can't install Java Card applets onto SIM without a key, which only the operator of the SIM has.
You can only install an applet if you have a developer SIM where you know the key or if you have somehow the luck to get a SIM where you don't need the key.
Note: use only decimal numbers for parameters Most RIL (radio interface layer) implementation for Android is relying on the CRSM (restricted SIM access) AT command for providing SIM IO service.Each SIM has its own Passcode, called , which can be lifted by entering the SIM card’s PIN. However, if you type the wrong PIN more than 3 times, your SIM card is permanently locked and can be recovered only with the PUK code. However, this espouses your SIM cards info in case of thefts.If an unauthorized person gets his hand your i Phone and extracts the SIM card, you might experience a data leak, because the SIM can be used with another smarptohne, if SIM lock isn’t available.But (1) is risking to use non-available or OEM dependent Thus (2) might actually be a better choice, from simplicity point of view....
