Turn cellular off or on

Your AppleWatchUltra with an activated cellular plan uses the best network connection available to it—your iPhone when itʼs nearby, a Wi-Fi network that you’ve connected to previously on your iPhone, or a cellular connection. You can turn cellular off—to save battery power, for example. Just follow these steps:

  1. Press the side button to open Control Center.

  2. Tap Set up and use cellular service on Apple Watch Ultra (2), then turn Cellular off or on.

The Cellular button turns green when your AppleWatchUltra has a cellular connection and your iPhone isn’t nearby.

Note: Turning on cellular for extended periods uses more battery power (see the AppleWatch General Battery Information website for more information). Also, some apps may not update without a connection to your iPhone.

Check cellular data usage
