Is cellular worth it for your Apple Watch

Is your iPhone glued to your hip so to speak? If so, then a GPS only model will do everything the cellular model will do because your iPhone will always be nearby. Where nearby can be in the bedroom while you are in the kitchen (assuming a reasonable sized 3-4 bedroom home).

A cellular model can leave the iPhone at home while you go for a walk, run, bike ride, etc... and still receive phone calls, messages, email, etc...

NOTE: A GPS model can leave the iPhone at home while exercising and it will track your exercise and transfer the data to your iPhone when you get back home.

PS. I'm a GPS only use and my iPhone is always nearby, so I have been very happy with my GPS only version.

Only you can make that decision, for me it is $10 per month plus the usual array of fees and taxes. I am bad about leaving my iPhone at home (and once my favorite coffee shop) and I also dislike carrying my iPhone when I go for a walk at a nearby park and listen to Apple Music on my AirPods while I walk. For Bob this isn't a big deal. Everybody is different and you will have to make up your own mind.
