First, please fix your authorship information. See the AUTHORS file to
see what we expect. Also, please make sure that you're using tabs for
indentation and following the relevant coding style. See the Submitting
Patches section in the HACKING document in oFono git as well as
doc/coding-style.txt.

So my first concern is that whatever you do here also has to work for
LockPin and UnlockPin.

Have you considered querying the PIN state on a failure instead? If the
lock/unlock/change pin operation fails, then re-query the current PIN.
If the CPIN is no longer returning READY and we're in a state
OFONO_SIM_STATE_READY, then tear us back down to an earlier state.

What is the reason for excepting PUK2 here? Should we be also
proceeding to the SIM_READY state on SIM initialization if PUK2 is
required as well?

This seems a bit drastic, but fair enough...
