Is it possible to use Apple TV with cellular data?

Yes, it is possible to use Apple TV with cellular data, provided one has the means to share that connection with the Apple TV. Since Apple TV itself does not have a cellular modem, it must connect to the internet via Wi-Fi or an Ethernet connection. Users can utilize a smartphone's personal hotspot feature to create a Wi-Fi network from cellular data, which the Apple TV can then connect to. Alternatively, one could use a cellular modem or a dedicated mobile hotspot to provide a Wi-Fi signal for the Apple TV. However, streaming content on the Apple TV over a cellular connection might consume a significant amount of data and could quickly deplete a limited data plan.
