My device switches to Wi-Fi when I'm using mobile data to surf the Internet

Your device will automatically switch to a wireless network if the Wi-Fi is enabled and it detects a hotspot that it has been connected to before. Even if both Wi-Fi and mobile data are activated, the device will connect to the wireless network by default.

If you want to continue using the mobile data, please disable the Wi-Fi.

Otherwise, you can surf the Internet via the wireless network.
