I believe you're right that I'm looking at the default EPS bearer. What 
would be the simplest way to only use CID>=1 for Fibocom modems? The 
fibocom plugin uses the default connect_3gpp method for context 
selection, configuration etc. Is there a simple way to restrict the CID?

Speaking of the default EPS bearer, should ModemManager be aware of that 
bearer somehow, i.e. list it as an active bearer object etc?

Best regards,
Sven
