A:AnswerThe 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.
A:AnswerI use T mobile. There was a problem setting up the cellular service on the Apple Watch with T mobile. They have many poorly trained people at Tmoble. I finally found a smart tech lady who set everything up. It’s easy if you what to do.
A:AnswerYes, I currently have the xr but you'll need to update your phone to the lasted iOS update. Which will probably slow your phone down but so far it's been good with my watch. However I am looking into upgrading my phone as well.
