LTE EC25 Mini PCIe

IoT Modules LTE Standard Module

Hello, I have LTE EC25 Mini PCIe module on my main board. I connected my module to my computer via USB and established a connection. When I connect through Qnavigator, I receive responses to commands like AT, ATI, ATE1; however, I get an error “AT+CPIN? +CME ERROR: SIM not inserted.” I believe I need a firmware update. Am I wrong? I don’t know where to find the latest firmware. The response to the ATI command is as follows:
Quectel, EC25, EC25EFAR06A16M4G.

Best regards

hi，
The current firmware version is very new. You can check to see if the SIM card is inserted properly, and then restart the module.
