This is a tool that helps you quickly change and lock the 5G mode of your network to have a more stable internet. In addition to 5G, this tool can lock 4G LTE or any other type of network. It should be noted that some hate operators do not support voice communication over a 4G network, so you may not be able to receive calls while the 4G network is locked. To fix this problem, when you no longer need the Internet, return to automatic network selection.
