Hi @Jskim
The use case for Modem support on VOXL 2 Mini is through the USB Host port, J3, as shown here:

We provide up to 900mA of 5V output on VBUS, so be sure your power needs can work within that limit.

I'm sorry I cannot answer the other question, so hopefully someone else from the team will respond and advise.
Thanks!
