4G LTE Switcher is a smart app that allows phone networks to switch to 4G LTE or just use another network mode. We now support android 11+. This app is useful in areas with weak signal, causing 4G LTE smartphones to be forced to use 2G/WCDMA/HSDPA/3G networks. Usually, if the 4G network is not good, internet speed will be slow and special 4G data packets will go unused. With this app, the data packets won't go to waste when you're in an area with a lack of 4G network coverage. Please note: 1
