All Galooli gateways communicate with the servers through the cellular network, so all units have SIM cards for communication.
The only difference between the gateways is that in some gateways like ELARA/CORONA gateways the SIM card is removable and in other gateways like SPARTA, the SIM card is a component that is assembled (soldered) on the electrical circuit (E-SIM). E-SIM behaves completely like a regular SIM card.
