Quectel Ec25 Change Imei __exclusive__ Jun 2026

If the IMEI reverts after a power cycle, the module may have a hardware write-protect enabled or a customized firmware that pulls the IMEI from a secondary OTP (One-Time Programmable) memory.

Execute the write command by replacing the placeholder string with your target 15-digit IMEI. Ensure the number is inside quotation marks: AT+EGMR=1,7,"3562450xxxxxxxx" Use code with caution. Press Enter. If successful, the terminal will return: OK Use code with caution.

: Finally, instruct the modem to continue its normal boot sequence.

Searching for the phrase typically leads to fragmented information: half-working AT commands, warnings about legal issues, or outdated firmware guides.

Mobile network operators use the IMEI to identify device types (TAC allocation). Assigning an incorrect or invalid IMEI can cause the network to reject the module's registration requests. quectel ec25 change imei

Verify that the output matches your newly inputted 15-digit IMEI. Troubleshooting Common Errors

This command performs a full hardware-equivalent reset of the module. Wait roughly 10–20 seconds for the virtual USB COM ports to disconnect and reconnect to your computer. Step 5: Verifying the Changes

There is, however, one widely accepted legitimate use case: . A firmware update can sometimes fail and corrupt the module's internal storage (EFS), which may cause the modem to lose its IMEI and other critical calibration data, rendering it a brick. In this specific scenario, restoring the device's original, factory-assigned IMEI number is essential and is an act of repair , not fraudulent spoofing.

Conversely, some developers argue that the ability to change the IMEI is a necessary feature for repairing bricked devices and for testing in controlled environments, especially since the EFS area is prone to corruption during unofficial firmware flashing. If the IMEI reverts after a power cycle,

Quectel modules use a specific write command for the IMEI. Replace 123456789012345 with your target 15-digit number. AT+EGMR=1,7,"123456789012345" Expected Response 4. Save and Restart

Quectel modules use a specific command to write the primary IMEI. Replace 123456789012345 with your target 15-digit IMEI. Type the following command and press Enter: AT+EGMR=1,7,"123456789012345" Use code with caution. AT+EGMR : Enhanced General Modern Commands. 1 : Indicates a "write" action.

According to user reports, the command typically returns OK if successful. However, a user on the GL.iNet forums noted that this command often fails on newer EC25 modules, suggesting that Quectel or device manufacturers have actively begun locking down or restricting this capability in recent hardware revisions and firmware updates.

In conclusion, while the Quectel EC25 architecture allows for the modification of the IMEI through specialized serial commands, the practice is fraught with legal risk and technical danger. Users should prioritize working within the legal frameworks of their region and focus on legitimate configuration methods for network deployment.

If the above command fails, try the alternative syntax structure: AT+EGMR=1,5,"123456789012345" Use code with caution. Or simply: AT+CGSN="123456789012345" Use code with caution. Method 3: Using the Quectel +QNV Command (Advanced)
