Ubidium contains a 4G/LTE module for connecting to the internet via a mobile network, this module supports fallback to 3G/2G where available.
If a SIM card is present then the system will always automatically try to connect to the network regardless of whether or not cloud services are enabled.
The modem has support for both an internal SIM card, provided by RACE RESULT, and a secondary external SIM card port located with the main system Ports.
Note that at this time the internal SIM cannot be used for connecting the system online for timing unless otherwise stated by RACE RESULT.
