According to Openwrt Rooter firmware, the Fibocom L850-GL supports MBIM mode:

MBIM mode using the ATG+USBMODE=7 command
Is this possible from the Mikrotik Terminal?

What's the news since then? How supported is fibocom l850 in Mikrotik today?

As far as I remember, /lte at-chat support is included in ROS for this modem, starting with ROS 7.11.2rc and the command above should work.

/interface lte at-chat lte1 input=ATG+USBMODE=7

@Sertik
from version 7.11 in the changelog it says this

*) lte - added "at-chat" support for Fibocom L850-GL modem; so it should be compatible .

If you can though look for a 5G modem as it has bandwidth priority over the bts repeater ,and so with an LTE module you would always have lower performance.

sertik,
I thought you also , you have 5G DSS which is a very bad system that basically uses the LTE band and gives priority of use to 5G devices . Basically a fake 5G :?
PS the fibocom L850-GL can be found at 740 rubles really affordable!|

Help please: I have a Fibocom L850-GL modem, usb3 adapter and RB5009 (ROS 7.13.5). When I connect the modem to the router - LTE interface does not appear, in system/resource/usb the modem is visible, in ports/usb it is written in red usb1 and port inactive. No AT commands can be entered.
On PC the modem works, it connects to the network. Modem mode is MBIM.
The following is written in the logs: lte2 mbim: error: wdm send failed: 19
Modem firmware version: 18500.5001.00.05.27.16
Should I upgrade the modem to some other firmware version? Or what else can be done?
