Remote access to an UICC/eUICC¶
To access a card with pySim-shell, it is not strictly necessary to have physical access to it. There are solutions that allow remote access to UICC/eUICC cards. In this section we will give a brief overview.
osmo-remsim¶
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 UICC/eUICC 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.
To access remote cards with pySim-shell via osmo-remseim (RSPRO), the provided libifd_remsim_client would be used to provide a virtual PC/SC reader on the local machine. pySim-shell can then access this reader like any other PC/SC reader.

Android APDU proxy¶
Android APDU proxy is an Android app that provides a bridge between a host computer and the UICC/eUICC slot of an Android smartphone.
The APDU proxy connects to VPCD server that runs on the remote host (in this case the local machine where pySim-shell is running). The VPCD server then provides a virtual PC/SC reader, that pySim-shell can access like any other PC/SC reader.
On the Android side the UICC/eUICC is accessed via OMAPI (Open Mobile API), which is available in Android since API level Android 8 (API level 29).
