Connection terminated. 

That's the problem; from the logs I'm assuming that the ordering of the
statements is correct, and that these lines come before NetworkManager
starts the IPv4 timeout.  How long is the delay between the "Connection
terminated." line and the "Stage 4 of 5 (IPv4 Configure Timeout)
scheduled..." line?  We'll need to know that before we can figure out if
PPP is failing or if there's something wrong with nm-ppp-plugin sending
the information back to NM.

I may be wrong, but I believe the E3276 doesn't support PPP.  At least
not in the default (vendor supported) modes.  It requires using cdc_ncm
for the data channel and AT^NDISDUP etc for connection management.
