\subsection{Osmocom SIMtrace2 Card Emulation}
\begin{frame}{SIMtrace2 {\em card emulation} / {\em remote SIM}}
\begin{itemize}
\item The SIMtrace2 hardware can emulate the physical SIM card interface
\item This means that SIMtrace2 is connected to SIM {\em instead} of a SIM
\item The communication is picked up and passed via USB to the host
\item Host can now, for example, forward this communication to a (remote) smart card reader with the actual SIM
\begin{itemize}
\item {\tt simtrace2-cardem-pcsc} is a simplistic implementation of that: Pass communication to a locally connected PC/SC compatible reader
\item The {\tt osmo-remsim} software suite is a comprehensive software package for managing a fleet of phones/modems and SIM cards, allowing dynamic assignment of remote SIMS to phones/modems.
\item See a previous OsmoDevCall
(\url{https://media.ccc.de/v/osmodevcall-20210827-laforge-osmo-remsim}) for a talk on that

\begin{itemize}
\item a proprietary board hosting two SAM3S with SIMtrace2 {\em cardem} firmware
\item each SAM3S serves two cellular modems in mPCIe form-factor
\item can pick up SIM signalling of four modems and pass it to remote SIMs
\item Product page: \url{https://sysmocom.de/products/lab/sysmoqmod/index.html}

\item allows SIM tracing and card emulation/forwarding without any flex cables
