Telemetry

GSM/LTE

Before GSM telemetry can function, a SIM-card equipped with a data plan must be installed into the RBRcervello.

The end-user is responsible for provisioning a SIM-card and a data plan for use with the RBRcervello. To determine specific data quota requirements for your deployment scenario, please contact RBR.
