A:AnswerThe Iwatch 7 comes with a charging cord. You have to purchase the adaptor from apple in order to use it. I had a previous Iwatch and the charger cord from that works. Apple has gone to their new usb/c charging adaptor. It was another $20 for that.
A:AnswerNo, you don’t. You only need to connect this via bluetooth with your iPhone. Just in case you want to use a cellular plan, you will need to buy the Apple Watch + Cellular.
