What's the difference between Wi-Fi and internet? The internet is a global network linking all the computers and databases around the world – Wi-Fi is the wireless network that allows you to connect your devices to the internet.
Unlimited data on a phone refers to the Internet connection over the cellular network and does not use or require WiFi.
Can you use a laptop without Wi-Fi? Yes, you can still use your laptop without the internet for tasks or apps that don't require internet. However, if you don't have an internet connection but still need to be online on your laptop, you can connect it to a hotspot from your cell phone.

Wi-Fi connects to a router, cellular data does not.
To use it for Internet access, your tablet or smartphone connects (over Wi-Fi) to a wireless router—like the one you access at home or at your favorite coffee shop.
On LTE phones it will dramatically increase connect speeds.As others have said, when both WiFi and 3G are simultaneously connected, only WiFi will work. It will only used one of them, which one is the used first or selected.

One option for getting Wi-Fi anywhere is satellite internet. Much like satellite cable on your TV, this involves sending a signal through a modem to a satellite dish, then to an orbiting satellite. The signal is then bounced back to your dish, your modem, and your connected device.
Screen mirroring that uses wireless display technology like Miracast actually creates a direct wireless connection between the sending device and the receiving device. Therefore, no Wi-Fi or internet connection is required to mirror your phone screen onto your smart TV.
