Ok. I have narrowed it down a little.

It seems to be the CRSM command reading the
SIM_EFLI_FILEID when it succeeds.

ofonod[6326]: > AT+CRSM=192,28421\r
ofonod[6326]: < \r\n+CRSM: 144,
ofonod[6326]: < 0,850D00046F05040001FFAA03020000\r\n\r\n
ofonod[6326]: < \r\nOK\r\n

goes no further....


HACK:

If I remove

	ofono_sim_read(sim, SIM_EFLI_FILEID,
         	                OFONO_SIM_FILE_STRUCTURE_TRANSPARENT,
                 	        sim_efli_read_cb, sim);

from src/sim.c, the code works, for me.


After i tried the above and it worked, i tried to re-enable the function 
  call above, and put a breakpoint in sim_efli_read_cb(), and the code 
execution never hit there.


NOTE:

After entering the pin code for the sim card, only SIM_EFMSISDN_FILEID 
is read from the sim card, but maybe that is intentional, since it succeeds.

Ryan
