In many jurisdictions, including the United States (under the federal Communications Act), the United Kingdom, and the European Union, altering or counterfeiting an IMEI is a federal or criminal offense.

If you have a legitimate need to restore a corrupted IMEI, your best course is to contact the (e.g. Lenovo, Dell) or the mobile network operator . They have authorised firmware tools that can recover the correct identifier.

Many online forums suggest that sending simple AT commands through a serial interface can permanently change the IMEI of an LTE module. For the Fibocom L850-GL, these claims are structurally inaccurate. The Standard AT+EGMR Command fibocom l850gl change imei work

: Correct Intel XMM7360 USB drivers to expose the AT/Command ports.

AT+CGSN=1

: This does not alter the actual low-level signaling packets transmitted from the hardware layer directly to the cell tower, meaning sophisticated carrier firewalls may still detect the physical device profile. Switching Modes (PCIe to USB) Thinkpad and Fibocom modem: change IMEI? They have authorised firmware tools that can recover

(Intel XMM7360) is significantly more difficult than on Qualcomm-based modems because it lacks a standard "engineering mode" for permanent IMEI writes.

: By default, the L850-GL operates over a high-speed PCIe interface rather than a standard USB configuration. To interact with the device via terminal tools, developers often must use open-source scripts to flip the modem into an alternative mode. Community Workarounds and How Modifications "Work"

The modem must have an unlocked or engineering firmware installed. The Standard AT+EGMR Command : Correct Intel XMM7360

Fibocom L850GL Modem IMEI Change: Comprehensive Technical Guide

: Changing the IMEI on a Fibocom L850-GL is possible if you have an older firmware revision and the right leaked tools. However, for most users, it does not “work” reliably due to security hardening, legal restrictions, and the risk of bricking.

In many countries, altering an IMEI is explicitly . The rationale is straightforward: IMEI numbers serve as the primary mechanism for identifying stolen devices and blocking them from mobile networks. Changing an IMEI can be used to disguise a stolen phone as legitimate or evade network blocks.

A: No. Carrier lock is separate (SIM lock). Changing IMEI does not remove SIM network unlock.
