modules may need to be switched from to USB mode or MBIM mode using tools like the xmm7360-usb-modeswitch or the command AT+GTUSBMODE=7 to allow for such communication. Why Users Change the IMEI
The L850-GL is a Qualcomm chip (it's Altair). Therefore standard QPST/QRCT will not work . For Altair chipsets, the only official way is Fiboco’s proprietary download tool (not publicly available) or factory jtag/flasher . fibocom l850-gl change imei
Because the L850-GL often operates in PCIe mode (common in Lenovo/HP laptops), it is difficult to send AT commands directly. xmm7360-usb-modeswitch: This tool on modules may need to be switched from to
Changing an IMEI is illegal in many countries (e.g., the UK and India) and typically violates your carrier's Terms of Service. Risk of Bricking: For Altair chipsets, the only official way is
is a high-performance LTE CAT-9 module based on Intel hardware, commonly found in laptops like Lenovo ThinkPads.

: Send AT+CGSN and press Enter. This command returns the current IMEI of the module.
