The Fibocom L850GL is a popular cellular module used in a wide range of applications, from IoT devices to industrial routers. One of the key features of this module is its ability to support multiple frequency bands and networks, making it a versatile solution for developers and manufacturers. However, there may be situations where you need to change the IMEI (International Mobile Equipment Identity) of your Fibocom L850GL module. In this article, we will explore the reasons for changing the IMEI, the process of doing so, and the potential risks and considerations involved.
If that returns OK , you’re ready. If ERROR , try:
is a powerful tool, it is important to operate within legal boundaries. Changing the IMEI is rarely necessary and often illegal. For developers needing to test network compatibility, there are legitimate, legal avenues for provisioning devices. This link or copies made by others cannot be deleted

(which is based on the chipset) is significantly more difficult than on modems with Qualcomm or MediaTek chipsets. Unlike those brands, which often use simple AT commands like AT+EGMR , the Intel-based
Operators have detection mechanisms. If an invalid or blacklisted IMEI is detected, the device will be permanently banned from the network. Legal and Ethical Considerations IMEI manipulation is heavily regulated.
