swSIM is an all-software SIM card. It's the first publicly available (to the best of my knowledge) SIM card simulator which does not rely on any SIM hardware to work.
In summary:
- A software-only SIM card simulator.
- It does NOT depend on any hardware to work.
- Can attach to the PC through a software-only PC/SC reader and show up as a PC/SC card.
- The PC/SC interface allows it to connect to ANY phone with a SIM card slot and e.g. the SIMtrace 2 device running on the cardem firmware or any other tool which forwards messages to and from the phone.
Make sure to have make and gcc installed. Also make sure that you clone the repository recursively so that all sub-modules get cloned as expected.
The make targets are as follows:
- main: This builds a swSIM executable.
- main-dbg: This builds a debug swSIM binary with debug information and the address sanitizer enabled.
- clean: Performs a cleanup of the project and all sub-modules.
Take a look at the usage message. You will need a file system definition (examples present in /data) or a .swicc file system file before running. swSIM is a client so make sure to start a swICC server beforehand (like that in the PC/SC reader for swSIM).
