Changing the IMEI to an invalid format (failing the Luhn algorithm check) can cause the baseboard processor to reject network registration. Ensure your test IMEI is structurally valid.
or outright prohibited because it can be used to bypass blacklists or disguise stolen hardware. But for Elias, this was a matter of digital survival.
Once the module completes its boot cycle, reconnect the terminal emulator and verify that the change was successful. Run the verification command: AT+GSN Use code with caution.
Many Quectel firmware revisions support the standard enhanced configuration command structure. To write a new IMEI, use the write command format: AT+EGMR=1,7,"123456789012345" Use code with caution.
If the command returns OK , the new IMEI has been temporarily written to the volatile memory buffer or queued for storage. To ensure the module initializes correctly with the new parameters, issue a reset command: AT+CFUN=1,1 Use code with caution.
AT+EGMR=1,7,"[15-digit IMEI]"
