What is the exact meaning of the
LAST ACTIVE timestamp on the dashboard?
Is the the last time the device had power and was in signal range of a compatible cellular network?
Or is it the last time the device successfully sent or received user data?
Is there a way o check if a device is currently powered up and Connected to a cellular network?
Is there an SMS “ping” on the Nova modem where I can send it a specially formatted SMS message that will cause the modem to automatically reply so I know that it currently has cellular connectivity?
