It's trying to see if the SIM card is ready to be used. Usually after the SIM PIN unlock operation the SIM card may need some time to get initialized; if we're too quick asking things after that we may get errors. See this example I just got yesterday with a different modem: ModemManager[20729]: <debug> [1488923142.478228] [mm-broadband-modem.c:6418] modem_messaging_load_initial_sms_parts(): Listing SMS parts in storage 'sm' ModemManager[20729]: <debug> [1488923142.478249] [mm-broadband-modem.c:5532] mm_broadband_modem_lock_sms_storages(): Locking SMS storages to: mem1 (SM), mem2 (none)...
