So I pulled the T-Mobile 5G Business Internet card from my Nighthawk M6, and I get:

root at OpenWrt:~# uqmi -d /dev/cdc-wdm0 --uim-get-sim-state
{
        "card_slot": 1,
        "card_application_state": "ready",
        "pin1_status": "disabled",
        "pin1_verify_tries": 3,
        "pin1_unlock_tries": 10,
        "pin2_status": "not_verified",
        "pin2_verify_tries": 10,
        "pin2_unlock_tries": 10
}
root at OpenWrt:~# 

So it's not a problem with the slot.  But I also don't see the "qim" interface coming up:

Looks like the documentation here:

https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle

Isn't exactly right.  And this part of my /etc/config/network mismatches:

config device
        option name 'br-wan'
        option type 'bridge'
        list ports 'eth1'

config interface 'wan'
        option device 'br-wan'
        option proto 'dhcp'

config interface 'wan6'
        option device 'br-wan'
        option proto 'dhcpv6'

config interface 'WWAN'
        option proto 'dhcp'
        option device 'usb0'

config interface 'WWAN6'
        option proto 'dhcpv6'
        option device 'usb0'
        option reqaddress 'try'
        option reqprefix 'auto'

config interface 'WWAN_Q'
        option proto 'dhcp'
        option device 'wwan0_1'

config interface 'WWAN6_Q'
        option proto 'dhcpv6'
        option device 'wwan0_1'
        option reqaddress 'try'
        option reqprefix 'auto'

config interface 'qmi'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        ##option device '/sys/devices/platform/soc/11200000.usb/usb4/4-1/4-1.1'
        option apn 'fast.t-mobile.com'
        option auth 'none'
        option pdptype 'ipv4v6'
        ##option pdptype 'ipv4'
        ##option apntype 'default,supl,mms'
        option plmn '310260'
        option modes '5gnr,lte,umts'
        option dhcp '1'
        option autoconnect '1'


Guessing I need to add "list ports wwan0" to "config device/option name br-wan".

Where is all of this other stuff being generated by?  What don't I need?

Thanks
