Changing the International Mobile Equipment Identity (IMEI) of a cellular module is a complex procedure often necessitated by regional regulations, network compatibility issues, or device testing requirements. When working with Quectel modules—such as the popular EC25, EP06, or RM500Q series—understanding how to "install" or reconfigure an IMEI requires a mix of specific hardware drivers, AT commands, and specialized software tools.
The most common method involves sending specific strings to the module's via a serial terminal (e.g., PuTTY, QCOM, or Minicom). 1. Identify the Correct Port Windows : Check Device Manager for "Quectel USB AT Port". Linux : Typically maps to /dev/ttyUSB2 or /dev/ttyUSB3 . 2. Verify Current IMEI quectel change imei install
The AT+EGMR method is often disabled in recent firmware. If you get ERROR , you must use QFirehose or QDM. or minicom (Linux) to send commands.
