The Apple Watch is a smartwatch that can be paired with an iPhone to access features such as cellular data and GPS. Here is some general information about how these features work on the Apple Watch:

Cellular data: The Apple Watch can be connected to a cellular network using a cellular data plan. This allows you to make and receive phone calls, send and receive texts, and use data-dependent apps even when you are away from your iPhone.

GPS: The Apple Watch has a built-in GPS receiver that can track your location even when you are away from your iPhone. This can be used for features such as location-based reminders, finding your way using maps, and tracking your workouts.

To use these features, you will need to make sure that your Apple Watch is set up correctly and that you have a compatible iPhone and a compatible cellular data plan. For more information, you can refer to the Apple Watch user guide or contact your cellular service provider.
