Turn cellular off or on
Your Apple Watch with cellular 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:
Touch and hold the bottom of the screen, then swipe up to open Control Center.
Tap
, then turn Cellular off or on.
The Cellular button turns green when your Apple Watch has a cellular connection and your iPhone isn’t nearby.
Note: Turning on cellular for extended periods uses more battery power (see the Apple Watch General Battery Information website for more information). Also, some apps may not update without a connection to your iPhone.

Try one of the following when connected to a cellular network:
Use the Explorer watch face, which uses green dots to show cellular signal strength. Four dots is a good connection. One dot is poor.
Open Control Center. The green bars at the top show the cellular connection status.
