Hi there,
I use the Nova with a Hologram SIM card. The SIM is working out-of-the-box on an Android Tablet.
The Nova is now plugged on our Linux board. Since I was not able to make it work with a provider file and a chat script, I went with AT commands to debug.
So I do: minicom -D /dev/ttyACM0 -b 9600 and get:

At the end one can see the NO CARRIER response.
I’m using a SOM, an iMX6ULL from Toradex with the Viola carrier board.
Thank you for your time.
