Celluar Connection unavailable - already updated firmware to 25.21.660

Have tried several times to engage the wwan0 using the beta configuration piece of sixfab connect. Have a ticket in with support, but it has been radio silent so I thought maybe someone could help here. Surely, it must be something simple I am missing. I have a Telit LE910C4-NF and the firmware has been updated to 25.21.660
Any help is appreciated
