Apple TV
Is there anyway to stream content from my iPhone XR to my Roku TV without using up my WiFi data? I am on a very restricted (60 GB) monthly data plan and am hoping that I can use my Apple TV (3rd generation) to watch videos that are not on YouTube, without eating up my WiFi data. I am able to watch them on my iPhone using cellular data, but it is a very small picture. Any assistance would be appreciated.
Thank you.
iPhone 7 Plus, iOS 11
