Does the GPS work independently of Cellular data? Or will it automatically switch to using cellular data if the signal is stronger? Also , Can I manage which applications use cellular data. I only want to use data for calls and text.
Apple Watch
Whenever possible all Apple Watch models will try to use low energy Bluetooth to the iPhone and use the iPhone's larger battery, and better radios & antenna.
A GPS only model does not have the option of using cellular, as it does not include the cellular radio circuits.
A cellular model will use its cellular radio when it can not use a lower power option, such as your nearby iPhone over Bluetooth.
Some cellular features still require an iPhone, such as SMS and MMS messaging.

Calls and text don't use your cell data, they use cell voice. If you want to use maps while away from your iPhone you will need cell data.
