Having an unstable network is indeed quite annoying. Besides being able to inhibit access to the internet, jumping networks can make the device's battery run out quickly.
But fortunately, you who use an Android device, you can lock the network as desired. For devices with an old operating system, you can even set it through the Settings page, then enter the Cellular Network menu.
And even on some new devices, such as devices made by ASUS or Xiaomi, you only need to use the dial code * # * # 4636 # * # *to display device info, to lock the network to the expected network.
But this is very different from Samsung devices. Although on older devices you can use the same method, for new devices you cannot use dial codes to lock the network.
Of course, this mode is disabled by Samsung, so you need to use third-party applications to do it. In more detail, you can follow the review on How to Lock the 4G Network in the following Samsung HP.

In addition, this setting will also disappear when the Samsung phone that you use is dead or restarted. So, you need to set it again when the phone is back on when you want to lock on the 4G network again.
Whereas to restore the network on the Samsung device that you use to the initial settings, you can do so by following the method described earlier or by restarting the device.
