How do I establish and IP connection to the WWAN of a Sierra Wireless MC7354?
I have a system with a Sierra Wireless MC7354 modem running Ubuntu 18.04.
ModemManager can see and control the modem.
$ mmcli --modem 0
returns lots of great information. (That's how I know the modem is an MC7354.)

The ports list shows several ports:

$ mmcli --modem 0 --simple-connect="apn=internet"
is successful
$ mmcli --bearer 0

How do I establish a connection on Ubuntu to use this interface?
$ ifconfig -a

How do I establish an IP connection to this device?
Thanks for the help!
