It still is R/W enabled , as the cell phone MCU communicates with it. what do you mean by limited access ?.

Assuming your building hardware to talk to the SIM card, you will first need the pin outs which are readily available here:
http://pinouts.ru/Memory/SmartCardIso_pinout.shtml

If you want the actual protocol, look here:
http://mobileforensics.files.wordpress.com/2007/03/sim-card-protocols.pdf

remember a SIM card at the lowest level is a microcontroller using a single line for Input/Output, and the behavior is similar to that of a smartcard. Look for an application called WinExp used in the satellite community to easily write scripts to talk to smartcards, and in this case could work to talk to a SIM card.
