osmo-remsim

Osmocom remote SIM software suite

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, entire fleet of modems/phones can be operated on, as well as banks of SIM cards and dynamically establish or remove the connections between modems/phones and cards. 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. It can also be used with other systems that use contact-based smart cards according to ISO 7816. Only the T=0 protocol with standard (non-extended) APDUs is supported.
