Where may I switch on/off LTE on my S4 mini (GT-I9195)? I don't have this possibility in setting (Mobile networks / ... see attached picture). Thanks for your answers.
Switch on/off LTE

Thanks. I did it. But when I ckeck settings there is same setings "GSM/WCDMA (auto connect). How do I know that the phone has been turned on LTE (ie except using the application that you suggested)?
The option will not show if your sim card / carrier / phone subscription does not have 4G enabled.
addition: this option is not shown in settings if the mobile operator is not the "whitelist", special file in the system named lteon_netlist.xml. This file is a part of CSC, placed here: /system/csc/common/system/etc
for example, russian mobile operator MTS is not in the list, so I had the same problem. To make changes to system files you need root access. Or you can use mentioned above by me method. It enables LTE but not showing option in the settings.

Just to clarify; so if my operator doesn't have 4G yet, the option will not show in menu???
Inserting SIM from 4G operator (vodafone) will enable the LTE option?
Well... Have to disagree with you.
Unlocked (SIM lock) my phone, restarted and LTE showed up.
That brings the conclusion : SIM locked ROM(s) have certain function disabled.
I was confused as flashed generic ROM (BTU and DBT) and still no LTE. After SIM unlock and restart LTE shows in option...

And also if your phone is SIM locked...
Your phone must be SIM unlocked and probably you'll need to flash generic (unbranded) ROM.Where may I switch on/off LTE on my S4 mini (GT-I9195)? I don't have this possibility in setting (Mobile networks / ... see attached picture). Thanks for your answers.

No LTE/WCDMA/GSM mode
Sorry for bringing up this old thread, but my problem is exactly the same.
So far I'm trying to follow instruction described here, but I'm not sure if the file persist.radio.lteon exists there. Having trouble with rooting my phone, in order to get access to that file, but I can do it I think.
Maybe, someone can add something here!
About my case: SIM is LTE ready (tested in Huawei G6, in the network of my current carrier, LTE on 1800, mode can be selected and works fine), also smartphone is working in LTE in general - used it with other SIM in Vodafone (CZ) and Omnitel (LT), Network Mode kindly allowed to choose LTE/WCDMA/GSM mode. In my current (home) carrier it's simply not there, just WCDMA/GSM.

That app says "device not supported"
What exactly does this mean - SIM unlock?Well... Have to disagree with you.
