Apple Watches do not require an iPhone to be connected to them for full functionality and can also run independently in a Wi-Fi or cellular connection environment. They are quite versatile gadgets, and you can use them as your only device when traveling internationally or for times when the phone is out of juice.
The Apple Watch can be set up to operate in total independence of the iPhone, and this includes being able to pay with Apple Pay at stores that accept contactless payments. You can also set up an Apple Watch to use Wi-Fi as a way of connecting to the internet and other services, which is perfect for times when you’re not able to use your iPhone.
You can use the Apple Watch to get notifications about email, SMS, iMessage, and other apps. The Apple Watch has a Nearby feature that shows you the location of your iPhone – when it’s close to you – so you’ll know when it needs charging.
All these capabilities require iOS 8 or later on an Apple Watch paired with an iPhone 5 or later that runs iOS 7.1.2 or later.
The only feature that requires an iPhone is called “Find My Watch,” which is available in addition to Find My iPhone in Settings > ID & Passcode > Toggle Find My iPhone on at all times.
