Nope, not really.

The process is roughly like this:
- Load settings file.  Settings are stored according to IMSI of the SIM
- If no settings file is found, wait until MCC, MNC and SPN are known
- Run provisioning plugins (e.g. MBPI)
- If provisioning fails, make up a 'sentinel' context telling external
parties that no valid settings exist.

oFono can.  Connman only expects to manage a single Internet context, so
having multiple will not work there.
