nRF9160 DK v0.8.5

SIM and eSIM

The nRF9160 DK (Development Kit) is designed to support both regular and embedded SIM (eSIM). For this purpose, it has a pluggable SIM card socket 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 DK, switch SW8 can be used to select the eSIM. Connector P23 can be used to connect and monitor the traffic on the SIM interface.
