Enable LTE/4G on Samsung Galaxy J1 2016

Question

If a SM-J120H device with Android 5.1.1 shows "WCDMA/GSM (auto connect)" as its top "Mobile Networks=>Network Mode" option, is there any secret code that can enable a "LTE/WCDMA/GSM (auto)" mode instead?



In other devices it seems to involve dialing *#0011#.
