Use cell data to watch on a smart tv

If you have a 5G connection you have 2 options:

• You can use the Personal Hotspot. Just make sure that you don’t exceed its data cap
• If your TV supports AirPlay 2 you can bring up the program on your phone, then use AirPlay to view it on your TV

Here’s a list of AirPlay compatible TVs→Home app - Accessories - Apple

And AirPlay instructions→Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch - Apple Support

This has some chance of working. It has a higher chance if you have and use a 5G cellular data plan.
