osmo-remsim is a suite of software programs enabling physical/geographic separation of a cellular phone (or modem) on the one hand side and the SIM/USIM/ISIM card on the other side.
Using osmo-remsim, you can operate an entire fleet of modems/phones, as well as banks of SIM cards and dynamically establish or remove the connections between modems/phones and cards.
So in technical terms, it behaves like a proxy for the ISO 7816 smart card interface between the MS/UE and the UICC/SIM/USIM/ISIM.
While originally designed to be used in context of cellular networks, there is nothing cellular specific in the system. It can therefore also be used with other systems that use contact based smart cards according to ISO 7816. Currently only the T=0 protocol with standard (non-extended) APDUs is supported.
Please visit the official homepage for usage instructions, manual and examples.
You can clone from the official osmo-remsim.git repository using
git clone https://gitea.osmocom.org/sim-card/osmo-remsim
There is a web interface at https://gitea.osmocom.org/sim-card/osmo-remsim.
The User Manual is [optionally] built in PDF form as part of the build process.
