All Galooli gateways communicate with Galooli’s cloud environment through the cellular network, there for all the gateways have SIM cards for communication.
The only difference between the gateways is that in some gateways like ELARA/CORONA 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.
