Can I wire his device to the Roku TV to play content from his phone on the tv?
I am helping a friend who has unlimited data on his phone but no internet at home. I was looking to do screen mirroring from my iPhone to the tv to see if it works before he buys a new phone. (Switching from android to iOS)
Does he have to wire his device to the Roku TV to play content from his phone on the tv?
You can use AirPlay to mirror exactly what you see on your Apple device to your Roku TV. However, one requirement for AirPlay to work is that both the Roku and the iPhone need to be connected to the same wireless network. Perhaps you can use a separate device that will serve as a hotspot for the Apple and Roku TV to connect to.
