Note: The 1,7 parameters specifically target the IMEI storage in the module's NVRAM.
To change the IMEI, use the AT+EGMR command with the write parameter. Command: AT+EGMR=1,7," " Example: AT+EGMR=1,7,"351234567890123" Response: If successful, the module will return OK . 4. Restart and Verify To make the change active, restart the module. Restart: AT+CFUN=1,1
Before proceeding with any IMEI modification, you must understand the legal landscape. Quectel explicitly states that , and the company provides no official command or support for such modifications.
