How to switch from 5G to LTE data in galaxy s21 in settings? Or I have to call verizon tech department? Currently I have unlocked Galaxy S21 and want manually to be able to switch between 5G and LTE data speeds. I can not do it. When I try to switch it in "mobile network"-"network mode" from automatic to manual it gives me a list of network operators but an option to switch from 5G to LTE. I want to switch to LTE to save battery use time. Also, from reddit user: iphone 12 max on verizon is able to do it in settings.
