Hi Lukasz,
I am still a little bit confused about ofono_gprs_cid_activated(). As far as I can see only atmodem calls it. No other driver does that.
That's because only the ublox devices have been properly enabled for LTE :)
I am not sure if a context is automatically created. I can see that the sim card has a few profiles, and the user can select which APN to use, start/stop ip network, etc.
Yes, that's how LTE works. An initial context (default bearer) is always activated on LTE. The device can provide an initial attach APN (see doc/lte-api.txt) which is used to tell the modem which APN to attach to by default. From what I recall, the device can provide an empty APN (in which case the network assigns one).
The default bearer varies by the carrier. Some use it for IMS, some use it for the internet context. So the modem/firmware behavior is often tweaked for a particular carrier. Some modems might not report the default context at all in which case the device acts more like a 3G modem than an lte one.
