SIM Interface
The SIM pins provide the connections necessary to interface to a SIM holder located at
the host device. The Voltage levels over this interface comply with 3GPP standards.
The SIMIN line is not at the connector and is internally grounded.
In this mPCIE variants onboard SIM holder and eSIM are not mounted.
