So this is being managed in QMI, which is ok, but as seen above the
"current" mode is limited to cdma-evdo for some reason (i.e. no LTE).

Can you try to run this?
mmcli -m 0 --set-current-capabilities="cdma-evdo|lte"

The device should reboot after that; then re-run "mmcli -m X" (X will
likely be 1 after the reboot) and see if the "current" field shows
"lte" as well.

[greg@dell-wifi ~]$ sudo mmcli -m 0 --set-current-capabilities="cdma-evdo|lte"

error: couldn't set current capabilities: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: Setting capabilities is not supported by this device'

I am asking the guy I am incorporating this for to check his plan to see if his SIM card plan is even LTE capable.  He is switching from T-Mobile 2g on his devices (since they are disbanding that network) to Verizon.  I'll post back when I hear, but your earlier comment that evdo does not take APNs took me by surprise.  I have never used 3rd party network subscriptions before until this guy, but what you are saying is that when using PPP on evdo networks there is no APN concept like in GSM?  His original line of product on T-Mobile 2g was able to use 3rd party APNs just fine - I did not know the backend of the 2 technologies were that much different other than the framing used - guess I need to read up more.
