I have a new Grand X Max 2 and I can't find where to choose the network mode. Settings > Mobile networks > Mobile Data simply asks if I want to allow the phone to access data over mobile networks and Settings > More has nothing. What gives? Hardreset seems to think that this is possible, but I don't see any of those options.
I tried *#*#4636#*#*, but that didn't seem to do anything. I bought a booster for the house that worked fine when I could set 3G as the preferred network, otherwise my reception is poor.
How can I choose a preffered network to exclude LTE?
