2G 3G 4G LTE Switch lets you toggle between 2G,3G,LTE,4G and 5G modes. It actually opens the built in network setting screen but saves your 2-3 taps each time. If you frequently toggle between 2G/3G/4G/5G or LTE mode, this application might save some of your clicks. *** Before giving an invalid rating read this first. It is just a tiny bookmark App to open the network settings directly. You surely can do this without this App but it helps when you keep on switching network modes several times.
