Hello Quectel Team,

I would like to check whether my EC200U-EUAA module is running the latest firmware version.

Current firmware information:

ATI:
Quectel
EC200U
Revision: EC200UEUAAR03A03M08

AT+QGMR:
EC200UEUAAR03A03M08_01.200.01.200

Could you please confirm if this is the latest firmware available for the EC200U-EUAA module?

If a newer firmware version is available, could you kindly provide the latest firmware package and the corresponding upgrade tool/instructions?

Thank you for your support.

Hi Sir,

Thank you for sending the latest firmware version (EC200UEUAAR03A23M08).

However, after upgrading to this firmware, I am facing an issue where the SIM card is no longer being detected. The same SIM was working correctly before the firmware update, so the problem appears to have started only after the upgrade.

Could you please help me with this issue? If available, would you be able to provide a stable firmware version that is known to work reliably with SIM detection on the EC200U-EU module?
