nRF9161 DK v0.9.1

SIM and eSIM

The nRF9161 DK is designed to support regular Subscriber Identity Module (SIM) and Embedded SIM (eSIM). For this purpose, it has a pluggable SIM card socket (J5) that takes a nano-sized SIM (4FF) and a non-populated footprint for an eSIM (MFF2).

Using the SIM socket is the default. If an eSIM is soldered on to the Development Kit (DK), the interface MCU application switch SW7 can be used to select the eSIM. Connector P28 can be used to connect and monitor the traffic on the SIM interface.
