apple watch 4 - cellular vs. non cellular
Hello,
i would like to ask what is the difference between apple watch 4 cellular and non cellular? I mean in everyday use, when i have iphone always in my pocket. I would love to use apple watch 4 as an assistant for notifications of my emails (Gmail app), viber, messenger, apple music, sms, phone calls (via AirPods) etc.
I do not need apple watch 4 to use seperatly from iphone but my question also is, if i use cellular data on iphone, will the GPS only apple watch model drain data through iphone ?
Thank you very much.
John.
