Our device guides will help you with setting up and using your Apple Watch
You need an iPhone to use a non-cellular Apple Watch. Pair your devices using the iOS Watch app. If you don't have the app, search for Watch in the App store.
You can use a cellular Apple Watch without an iPhone, but make sure you use a model that's supported on UK networks. If you didn't get your device in the UK, check if it's compatible on the Apple website

To connect your Apple Watch to your phone you need Vodafone OneNumber
If it isn't already included in your plan you'll be asked to subscribe as part of the set up. Then open the iOS Watch app on your iPhone, scroll to Cellular and follow the onscreen instructions.
If the Watch app isn't on your device, search for Watch in the App store.
Existing OneNumber Watch customer
If you've received a replacement watch or upgrade, then your old SIM might not fit and you'll need to do a SIM swap
When you've done that, pair your device with your watch using the iOS Watch app on your iPhone and follow the onscreen instructions.
