TVS don't have wireless Internet access because phones and TVS have different designs and functions.
The phone has a built-in wireless network module that can connect to a Wi-Fi network, so you can surf the Internet wirelessly. TVS are designed to be home entertainment devices, not Internet access tools, so most don't have built-in wireless networking modules. While some smart TVS can now connect to Wi-Fi networks, not all TVS support this feature. In addition, larger TV screens and higher resolution require more data to be transmitted, which requires a more stable and faster wired network connection, while wireless networks are relatively limited in transmission speed and stability.
Therefore, mobile phones can access the Internet wirelessly, while televisions generally need to be connected via a wired network.
