In this tutorial, we show you how to enable LTE only or 4G only mode in Samsung phones. Why you need LTE only mode in your phone? With LTE/4G connection you can enjoy uninterrupted video streaming, video call, HD audio call and more. However, if you are in an area where 4G LTE signal is poor, your phone will automatically switch between 4G/LTE, 3G, EDGE or 2G radio to be able to provide data connectivity.

So, to get constant LTE/4G connection on your phone, you should be in an area where 4G LTE reception is good and enabled the LTE only mode in your mobile phone.
