Which Plan is better Paired or Unpaired and what's the difference?
A paired plan (personal paired plan): Your watch will ring when your phone does and you can leave your phone at home and still receive calls on the watch when someone calls your phone. You want this plan if you are having the watch yourself or are giving it to someone who already has a iPhone.
An unpaired plan (family member plan): The watch is a stand alone device and is not connected to an iPhone at all. You still need an iPhone to set it up and that device is the control device of that watch. This type of plan is good for parents who want to give a watch to their child so they can keep track of them and see where they are, they also can control who they can call from the watch. Think of it as a phone on your wrist.
