The amount of phones supporting this is very limited, according to some people older Siemens and Alcatel phones let you do this.Also older i Phone’s (3GS/3G/2G) let you do this if you are jailbroken (you need to install minicom from Cydia then connect to the device /dev/tty.debug).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.Your i Phone can remain connected to the web as long as you’re in the range oft a Wi-Fi hotspot. This means that you can use pop up will show up on your screen to notify you that you aren’t able to dial calls, until you don’t type the 4-digit PIN code. We’ll occasionally send you account related emails.

Thus (2) might actually be a better choice, from simplicity point of view....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 have previously looked at the possibility of using the modem AT command interface, but we need other alternatives in those cases when baseband does not present an available and proper AT command interface.
There are 3 other alternatives for reading the SIM EF / DF ( "multi RIL-client" does its access.
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.
