The file contains a TCP / IP configuration used for the interchange of data and by modifying this configuration, we can change the way our device connects to networks. With this change, depending on the device and the mobile network used, you could expect to see an increase in download and upload speeds while on Wi-Fi, 3G, and even 4G connections.
