I think I've found where the issue is. The MCC and MNC can't be 
retrieve. And the cause is the mnc length can't be retrieve in this 
callback:

static void sim_ad_read_cb(int ok, int length, int record,
				const unsigned char *data,
				int record_length, void *userdata)

The call returns at the test "if (!ok)". So, mnt_length stay at 0 and 
next, on IMSI callback, as it doesn't know mnc_length, it doesn't 
extract MCC and MNC.

I don't know why ofono call the callback with ok=0. In the log, I see 
the command was successful:

---------------

Mar 28 13:50:05 mr3000 ofonod[6859]: Data: < \r\n+CRSM: 
144,0,""\r\n\r\nOK\r\n
---------------

Maybe a clue on my problem... Why ofono says the command failed ?
