Please refer to the original bug report if more details are needed.


The Huawei plugin has already a "after-sim-unlock" step subclassed, which just waits 3s after a SIM unlock before going on with the initialization sequence (e.g. loading own numbers).

Some modems, like the Huawei K3520, may require even more time, though:

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

The after-sim-unlock step should be improved to make sure the SIM is fully initialized before going on; either looking for SIM busy errors or checking for "^SIMST: 1" indications.
