nrf9151 Hologram Soft Sim configuration

We are trying to evaluate nrf9151 for working with Soft-SIM.
Are there any instructions for configuring the Soft-SIM through AT command mode, or do I need to use another mode?

 
Configuration: nfr9151 dk out of box, FW version v2.0.2, Serial LTE Modem (AT command mode).
