A: No legitimate company offers such a tool. Any software promising “one-click IMEI change” for L850-GL is likely malware or a scam.
Common reasons (note: not all are legal):
A very rare subset of engineering or early-production modules can be modified using specific AT commands. fibocom l850gl change imei work
While writing a new IMEI is almost never legitimate for an end‑user, the IMEI is perfectly fine and often necessary:
The IMEI of an L850‑GL is stored in a non‑volatile memory partition and can be queried via standard AT commands. A valid IMEI consists of 15 digits, structured as follows: A: No legitimate company offers such a tool
While it is to modify the International Mobile Equipment Identity (IMEI) on similar hardware platforms using specialized AT commands or flashing firmware tools, successfully completing this process on the Fibocom L850-GL requires navigating unique chipset architecture, strict security levels, and significant legal and technical risks.

However, , so a method that works on firmware version 1.0 may fail on 1.2. While writing a new IMEI is almost never
Community discussions point toward the existence of such tools, but they are not widely shared due to legal and ethical concerns. On the Chinese forum Right.com.cn, a user asked for the same information and was told that “大体上需要调试软件还要配套的AT命令” – “you need debugging software and matching AT commands”. Another user mentioned “github上有软件，只能在Windows上改” – “there is software on GitHub, can only be changed on Windows”. However, attempts to locate a working, public GitHub repository for L850‑GL IMEI rewriting have so far been unsuccessful.
: Factory default state. The firmware is locked down. Most critical AT commands for low-level modifications will return an ERROR response.
: Instead of changing the IMEI, explore legal alternatives:
Most L850-GL modules come with a high security level that prevents the standard AT+EGMR commands from working.
