If your TV does not have an option for using mobile data, it means that it lacks the necessary built-in functionality to directly connect to the internet using cellular data. As a result, you may encounter limitations when attempting to utilize the hotspot feature from your iPhone.
The hotspot feature on an iPhone allows you to share your mobile data connection with other devices, such as a TV, that can connect to the internet. However, this process typically requires the TV to support specific wireless connectivity options, such as Wi-Fi or Bluetooth, which enable it to establish a connection with the iPhone's hotspot.
In the absence of a mobile data option on your TV, the TV's connectivity capabilities might be limited to traditional methods, such as wired connections (e.g., Ethernet) or connecting to a Wi-Fi network.
