How to Enable Band Selection Mode in Samsung [4 Methods]

In this guide, we will show you four different methods to enable the band selection mode on your Samsung device. By default, your Samsung device is automatically assigned the best possible network mode. However, there could still be a few instances wherein you might want to manually make a switch over to another band. For example, if you have found a new 4G LTE / 5G NR band in your area or you know of a well-known uncongested band, then you could manually make a switch over to it.

However, you wouldn’t be able to do so by the conventional method of heading over to the Settings menu. This is because the South Korean giant has hidden this network setting feature under its stock telephone app. So how could one access this functionality? Well, there exist two different methods through which you could enable the band selection mode on your Samsung device. So without any further ado, let’s check them out.
