LTE Failover with Internal mPCIE Modem Module

[DrDeed]

Hello, I'm still reading up on and troubleshooting out the issue, but I'm struggling with perhaps some of the basics behind an mPCIE modem and PPP.
For starters all the carrier documentation, just says to use their APN and then enable roaming. Which on a Netgear LM1200, that works as expected. However when I follow the opnsense documentation:
https://docs.opnsense.org/manual/how-tos/cellular.html

Everything seems great up until actually enabling it and checking the logs (see attached).
One thing I've noticed is articles where people are talking about how PPP isn't capable of 4G speeds, and that has me wondering if there's some basics here I'm by chance missing. The carrier doesn't have username/password options, they simply send out a SIM, and tell you to enable roaming and use their APN.

Any help, or points in the right direction would be great. Thanks!

Further exploration on the topic brought me to this article:

Which explains a lot, further research brought me to the below:

This leads me to the assumptions that unless something has changed, FreeBSD does not natively support 4g, and thus pfSense/OpnSense does not support 4g.
