Hi all!
JFYI, the SIM protocol dissector has finally been merged into wirshark mainline (svn rev. 40854). This means that the daily builds from https://www.wireshark.org/download/automated/osx/ and https://www.wireshark.org/download/automated/win32/ will now work out-of-the-box for SIM card tracing, without applying any patches.
Regards, Harald
