A:Answer The Cellular allows you to add it to your cell plan. For an extra fee, like 10.95 a month or similar, you can use your Apple Watch as a phone when you are not near your iPhone. For example, you could go out for a run and still use your watch as a phone. Of course this only works if you add it to your cell plan. My sister-in-law has the cellular version and plan but rarely uses it. Some parents want the ability to call their kids but don't want them to have all the cell phone functionality, so a cellular enabled Apple Watch is a great option.
