So you're mixing concepts here a bit.
gprs.c has two maps:
- pid_map
- cid_map
and two ids:
- pri_context::id
- ofono_gprs_primary_context::cid
Roughly speaking the cid_map lets us pick a context id that maps 1:1 to
the modem driver. Hence the use of ofono_gprs_set_cid_range. Basically
the driver tells us the valid range of context ids and oFono picks the
rest. For an AT modem the driver can simply use the cid picked by oFono
in activate_primary callback.
Internally oFono has another idmap for tracking unique ids for contexts
and ensuring some sane limit on their number. This is managed by
pid_map and pri_context::id.
The code you have right now would use the pid_map ids...

, but use the size of the cid_map in the CGDCONT=? implementation below.
These sizes are highly unlikely to match.
However, this brings up a more fundamental question from me. What do
you actually want to expose here? Do you want the emulator to be able
to view / edit contexts exposed over D-Bus?
Or is it enough to simply fake all this and maintain the cgdcont list in
memory for each emulator instance?
