The loading order of plugins

The bearer creation using CGDCONT is correct and the (S)WWAN activation
looks good. The connection logic looks correct so my guess is that the
issue lies in how the hardware/drivers are setup.

My AT^SSRVSET setup is value "1" ( ECM ), and I can't switch to value "10"
> ( NCM ).

I don't even see SSRVSET in the els61-e doc, odd, only in the '2'. Can you
give us any more detail on your WWAN interface? Do the USB0/USB1 interfaces
come up with Linux correctly? Can you use minicom on your ttyACM0 interface
to send 'AT+CGDCONT: 1,"IP","internet.mnc092.mcc466.gprs","",0,0'(redundant
but to be sure,[also are you sure your APN is correct]) and then
'AT^SWWAN=1,1,1'. Pending the hardware has been configured and loaded
correctly that's really all that needs to be done with this modem to start
the connection.

In your plugin are you using the same SWWAN logic, or something different
for your connection? If you can show us your plugin I'm sure we can figure
out the difference and get it fixed in the Cinterion plugin. Are you aiming
to use the WWAN interface for your connection or ppp?
