SIM cards

SIM cards in monitoring systems are used to provide communication between monitoring devices and the server. They play a key role in systems that require remote tracking and data transfer.
 
SIM cards are used in GPS vehicle trackers to transmit real-time location data. This allows you to control routes, monitor schedule compliance, and respond to deviations from the route.
 
SIM cards allow monitoring devices (e.g. GPS trackers, sensors) to connect to mobile networks to transmit location, status, and other parameters to the monitoring server.
This is especially important for devices that are on the move or in remote locations without access to Wi-Fi or wired networks.
