Sierra Wireless MC8355 - Gobi 3000

[Kenneth Berland <ken hero com>]

List,

Trying to get a Sierra Wireless MC8355 - Gobi 3000 working.  Without NM 
running, I can get the modem connected using mmcli and simple-connect. 
What is next to get an IP address?  NM tries to run dhclient on wwan0 but 
it times out.  Should this modem use QMI or PPP?  Does anyone have one of 
these running who can share their configs?

TIA,
Ken
