A:Answer Yes and no. You need the iPhone to set up the watch, and you need a cellular phone plan to which you will add a wearable. Once you are all set up, you can leave the phone at home and still get your emails, texts and such using the cellular connection. With the GPS only version, you would need to have the phone within Bluetooth distance, or the watch needs to be able to connect to a previously used Wifi network, in order to do emailing, texting, etc,
