FMC920 - SIM Initializing, ICCID 00, CPIN NOT READY

Martin PABLO a day ago

Teltonika FMC920
Firmware 04.00.00 Rev14

The device is detected correctly by Teltonika Configurator.

GPS works correctly:

  • valid position
  • 14 satellites in use

IMEI is visible.
Modem status: ON.

Tested with:

  • ThingsMobile SIM
  • Bouygues Telecom SIM
  • Smart Philippines SIM

Same behaviour with all SIM cards and even with no SIM inserted.

Configurator reports:

  • SIM Initializing
  • ICCID = 00
  • SIM State = Unknown
  • GPRS Deactivated

Modem diagnostic reports:
+CPIN: NOT READY

I have also tested a second Teltonika device with similar SIM initialization problems.

Has anyone seen this behaviour before?

Could this be caused by missing configuration, or does it indicate a modem/SIM interface problem?

Thank you.
