Description Dan Williams 2013-12-05 16:11:46 UTC 
On a Huawei K3520:

ModemManager[23814]: <debug> [1386259522.612855] [mm-at-serial-port.c:436] debug_log(): (ttyUSB2): --> 'AT+CNUM<CR>'
ModemManager[23814]: <debug> [1386259522.622586] [mm-at-serial-port.c:436] debug_log(): (ttyUSB2): <-- '<CR><LF>+CME ERROR: 14<CR><LF>'
ModemManager[23814]: <debug> [1386259522.622665] [mm-serial-parsers.c:364] mm_serial_parser_v1_parse(): Got failure code 14: SIM busy

While waiting just a bit works.  Maybe retry one or two times if we get a SIM BUSY?  I don't think we care about retrying if we get some other error though.

Maybe capturing "^SIMST: 1" unsolicited message sent after SIM-PIN entering will tell us when the SIM is fully ready to go on? That could go in the modem_after_sim_unlock() step in MMIfaceModem.

Moving bugreport to the new ModemManager bugzilla in fd.o; summarized the issue
there as well. Please subscribe to the new bugreport to get new updates.
