Access hidden network settings to force only 4g connection. This way you can change the network settings your device will not change the network modes and your internet connection will be uninterrupted. This is useful for playing games making video calls or any other job that requires a stable internet.

It should be noted that most network operators still do not support voice calls over a 4g network so you will probably not be able to receive voice calls while using this network mode. When you force 4g only the device cannot switch to 2g or 3g mode to receive the call. When you have finished using the application restore the settings as they were to allow the device to function normally. If you forget the settings go to system settings and select automatic network selection.

Also in the application you have detailed instructions on how to force 4g only as well as how to reset the settings to the defaults.
