We have a lot of FMB120 devices in our fleets and they are 2G devices.
Is there any hack by firmware from your side to convert them into 3G, 4G, 5G Suppoerted.
So that we overcome the inspections and traveling cost.
Please suggest an easy fix for that i will be waiting for your response.
I doubt that this is possible. According to this link
the hardware only supports 2G.
