A:AnswerYou do not need to have your phone with you. You can set up your Apple Watch cellular on your phone plan such that it will share a number with your phone even though it is actually a separate phone line (for which you will have to pay.) Our addition line on Verizon costs us $5 per month. The cellular coverage works essentially the same as it does on your phone.
A:AnswerAbsolutely and if you’re super active put a study cover over the watch face. The scratches are on a cover not my watch face and I changed my band from silicone to metal.
A:AnswerI believe you have to have an iPhone. The watch is basically an extension of the phone.
You could always contact Apple to verify for 100% accuracy.
A:AnswerI have small wrists and it still has plenty of room on it I’m not sure of the measurements if you need them I can get out a tape measuring tool and do that but you can use google to convert cm into inches as well. What doubles over is how much extra is on mine after I put it on and attach it. I got a s/m.
