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.
As you know, frequent switching between network connections will interrupt your video streaming, video call, and HD audio call. This will also drain your battery more quickly. 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.
If you own a Samsung phone and do not know how to enable LTE Only mode in it, then read on to know how to force your phone to use 4G LTE connection all the time. Keep in mind that you should be in LTE footprint or else you will lose connectivity.
