... no IP address, no route; maybe I should take this issue with the NetworkManager people?

Kind regards, Christian

Hey,


We may need NetworkManager logs to see why that connection attempt


wasn't completed correctly in the NM side.

NetworkManager_2019-08-28_15-24-08.log -- debug log



That's weird, because NM does say it's connected:

After the connection attempt, is the WWAN network interface configured

with an IP address (run "ip addr")? Is there a default route through

the WWAN interface (run "ip route")?
