Wi-Fi+

Once Wi-Fi+ is enabled, when your phone detects a Wi-Fi network that it has previously connected to or that is free, it will automatically enable Wi-Fi and connect to the network. Your phone will also evaluate the stability of Wi-Fi networks and switch to mobile data when the Wi-Fi signal is poor. Please note, this may incur extra charges.

1. Go to Settings > Wi-Fi .

2. Go to More settings > Wi-Fi+ and enable or disable Wi-Fi+.
