Osmocom SIMtrace

(C) 2010-2017 by Harald Welte laforge@gnumonks.org

SIMTtraceis a program that can be used for tracing the communication between a phone and the SIM card. More generally, it can trace any ISO 7816 based smart card interface.

SIMtrace is part of the Osmocom Open Source Mobile Communications project.

This repository contains a host program 'simtrace' as well as a patch for wireshark (which is part of mainline wireshark since February 2012)

The corresponding device firmware source code can be found at http://git.osmocom.org/openpcd/


The official homepage of the project is https://osmocom.org/projects/simtrace/wiki/
