Hello. I have a problem with the LTE band. I have an E3372 modem from a CP network.
I bought a better antenna and would like to set a different band but in CP after connecting the modem there is no change option, only LTE, 3G etc. There is no option to choose between 800MHz or 1800MHz. How can I change it? Because no programs that I found and read through the forums do not work.
I add a screan
