Ok, I understand what you mean now. 
 As the nRF9160 only has one SIM/UICC interface, so only one physical card is supported. Although, you might be able to add more using switches. 
 However, using eSIM, you can have multiple profiles on a single SIM card. In that case, there are two methods of remote SIM provisioning defined by the GSMA. 
 The first one is the "M2M solution". In that case, all the logic lies in the SIM card, and the servers the SIM card is talking to. The modem will provide the necessary communication channels to the SIM card, and which profile is used is managed remotely. 
 The other one is the "consumer solution". In this case, the user of the device can choose which SIM profile is being used. As this requires some form of interface for the user, this solution requires support in the application (specifically the LPA). Again, the modem will provide the necessary communication channels. 
 You can read more about the two solutions here: https://www.gsma.com/esim/wp-content/uploads/2018/12/esim-whitepaper.pdf
