Hello,
some years ago I have developed a working SIM card emulator for Silver Wafer Card (PIC16F877 and 24LC256).
It supports GSM 11.11 and GSM 11.14 standards and is fully functional inside cell phone (so far I have been using it for 10+ years).
Unfortunately it is written in somewhat rusty PIC assembly -- still it might be usable for your purposes.
I have published it on "https://github.com/vlp/ssim", so feel free to have a look.
Best regards
VLP

Hello,
wow, interesting. Do you have plans for a 'C' implementation? Do you have a permanent storage? Could you point me to that?
The file system is completely implemented in flash & ext.eeprom. You can see the file structure under src/files/3F00/**.
There is a make target 'files' that generates file system representation into src/files/files.inc -- it has to be run every time the files under src/files/3F00 change.
I have no plans regarding this old project -- I stopped working on it some years ago and just thought, that it might be useful for osmocom. To be honest I am currently quite busy :(
If you want open source implementation in high-level programming language I would recommend javacard -- IMHO better choice than cc32rs512.

A classic platform! :)

The code looks really great. Thanks a lot! I certainly think it will be useful.
