EG25-GC Firmware Request - Intermittent SIM Failure (CME ERROR 13) - GPD Win Max 2

Hello Quectel Support,

I have a GPD Win Max 2 with an EG25-GC LTE module experiencing intermittent SIM failures.

Current Module Information:

  • Model: EG25-GC
  • Current Firmware: EG25GGCR07A02M1G
  • Device: GPD Win Max 2
  • OS: Windows 11

Problem Description:
The modem intermittently loses SIM detection. When this happens:

  • Windows shows “Insert SIM” error
  • AT+CPIN? returns: +CME ERROR: 13 (SIM failure)
  • AT+CCID and AT+CIMI also return errors
  • The USB device remains visible in Device Manager
  • AT commands still respond (modem is not disconnected)

Recovery:

  • Toggling Airplane Mode ON/OFF recovers the connection
  • This indicates a software/firmware state issue, not hardware

Request:

  1. Please send me the latest firmware for EG25-GC (I understand version 30.202.30.202 or newer may be available)
  2. Please also send QFlash tool if required for the update
  3. Any recommended AT+QCFG settings for SIM recovery

My email for firmware delivery: steve@strazzy.it

Thank you for your support.

Best regards,
Stefano Strazzera
