Make calls over Wi-Fi
If your cellular carrier offers Wi-Fi calling, you can use your Apple Watch to make and receive calls over Wi-Fi instead of the cellular network—even when your paired iPhone isn’t with you or is turned off. Your Apple Watch just has to be within range of a Wi-Fi network that your iPhone has connected to in the past.
To see if your carrier offers Wi-Fi calling, see the Apple Support article Make a call with Wi-Fi calling, and enable Wi-Fi calling on your iPhone.
On your iPhone, go to Settings > Phone, tap Wi-Fi Calling, then turn on both Wi-Fi Calling on This iPhone and Add Wi-Fi Calling For Other Devices.

Note: You can make emergency calls over Wi-Fi, but when possible, use your iPhone over a cellular connection instead—your location information is more accurate. Make sure your emergency address is up to date—on your iPhone, go to Settings > Phone > Wi-Fi Calling, then tap Update Emergency Address. If emergency services can’t locate you, they go to your emergency address.
