I have the GL-X3000.
It combines some LTE bands with N78. (3_3_7_78). Can i make it to CA with also the other LTE bands like my S24 ultra?
Is it possible? Or because it's older modem there is no such capability.
As you suspected the CA combos are determined by the modem. This website may be of interest to you. https://cacombos.com/
Speedtest from S24 ultra: 900-1000mbps
Speedtest from Spitz 5G: 450-550Mbps
Is that normal? As i see, it can only CA 3 LTE bands together (no more)+N78 (5G). But even with that, it should be more speed.
Also when i check in tab for Cell Info , always shows ONLY 2 cells (1 LTE + 5G NSA band). I have to go to AT COMMAND in order to see all the bands. Why is that?
Finally, if i try to update the firmware of the modem, i will see any difference? How to check the firmware and how to update?
