Apple TV streaming

i don’t have WiFi at my place but have a jet pack from my job that I can’t use much data on and is otherwise expensive and not very effective in being a sole home WiFi system. However I can use it to set things up such as my Xbox (for updating and downloading purposes on occasion)

Now, let’s say I set up Apple TV and have a good data plan for my phone and just want to stream on a bigger screen using Apple TV. Would it work without constant wifi connection the same way I can use offline mode on my Xbox one? I’m willing to drop the dollar if I can just use it connecting with my phone. If anybody could help that’d be great. Thanks
