I have a Fibocom l-850 gl cellular module in my Thinkpad T15 and Windows 10 installed. There are often situations when the quality of communication from a mobile operator in 3G is better than in LTE. But the modem always automatically connectes to the LTE if any LTE signal exists. How can I force it...

I have Thinkpad T15 Gen1 20S60022RT .

This model has a SIM card slot and a place to install a wwan module (also antennas cables laid)

I also have a wwan module Lenovo ThinkPad EM7345 4G LTE (from the older model of notebook).
Will this module work in my T45?

Thanks!
