Quectel Change Imei Install Jun 2026

If the module reads the identifier correctly but cannot connect to the network, the identifier string may have an invalid Check Digit (the 15th digit computed via the Luhn algorithm), or the network has flagged the identifier allocation block. To help clarify any specific road blocks, tell me:

How to Change and Install an IMEI on Quectel Modules: A Comprehensive Technical Guide

To send commands to the module, open your serial terminal (like PuTTY or QCOM) and configure the connection parameters for the :

Permitted use cases:

Method B: NV Item Flashing via QPST (Advanced Qualcomm Calibration)

When AT commands are blocked or the IMEI is completely corrupted (e.g., after an improper firmware flash), you may need to use Qualcomm’s low‑level tools. This method is significantly more risky and should only be attempted by advanced users.

: Open your serial terminal and enter the following command to see the current 15-digit IMEI: AT+EGMR=0,7 Alternatively, AT+CGSN can be used to read the number.

Changing the IMEI on a Quectel module is technically possible using AT commands ( AT+EGMR=1,7,”new_IMEI” ) on many older and mid‑range modules, but it is officially unsupported by Quectel and often legally restricted. For modules with disabled AT commands or corrupted IMEIs, advanced tools like QFirehose or QPST may work—but at the risk of bricking the device. quectel change imei install

For mainstream modules like the EC25, EG25, and EM06, Quectel provides an explicit production configuration command: AT+EGMR=1,7,"123456789012345" Use code with caution. : Indicates a "write" action. 7 : Specifies the target parameter as the primary IMEI.

Run the Quectel USB Driver executable installer as an administrator. Restart your computer to finalize driver registration. Step 2: Connect the Module

This process should only be performed for legitimate development purposes, such as restoring an IMEI to a repaired board or testing private LTE/5G network authentication.

Furthermore, manipulating an IMEI is often used for device cloning or circumventing a network block, which is illegal in many countries.

(This commands restarts the module's full functionality and forces a power cycle reset). Step 6: Final Verification Post-Installation

This is the most widely discussed method and relies on a specific AT command that was historically supported on many Quectel modules but is increasingly being removed or disabled. The command is AT+EGMR .
