How do I know if I have a 3G cellular modem that needs upgrading to 4G LTE?

Cellular carriers are shutting down their 3G networks and this may affect your OPI Blue system.

As carriers shut off their 3G network your Gateway will stop reporting to the cloud and updating your grain conditions; if your system is connected with a 3G modem.  AT&T has already deprecated theirs.
