Set up your iPhone and FaceTime on Mac for phone calls
You can use the FaceTime app on your Mac to make and receive phone calls—including Real-Time Text (RTT) calls—when you set options on your iPhone and Mac. See FaceTime phone call requirements.
Set up your iPhone
On your iPhone, do one of the following:
iOS 18 or later: Go to Settings > Apps > Phone.
iOS 17 or earlier: Go to Settings > Phone.
Do one of the following, depending on your carrier.
If you see Wi-Fi Calling: Tap it, then turn on Wi-Fi Calling on This iPhone.
After you turn on Wi-Fi Calling, you may see an Add Wi-Fi Calling For Other Devices button. Tap it to allow calls using your other Apple devices that aren’t on the same Wi-Fi network as your iPhone, or if your phone is off. Otherwise, you can still use your Mac to make phone calls, but your iPhone must be turned on and on the same Wi-Fi network as your Mac.
Note: Only certain phone carriers support Wi-Fi Calling for devices that aren’t on the same Wi-Fi network as your iPhone. See the Apple Support article Make a call with Wi-Fi Calling.
If you see Add Wi-Fi Calling For Other Devices: Turn it on.
This option allows calls using your other Apple devices that are on the same Wi-Fi network as your iPhone.
Set up your Mac
After you turn on Wi-Fi Calling on your iPhone, turn on Calls from iPhone on your Mac. If you’re not asked to do so when you open FaceTime on your Mac, you can use FaceTime settings to turn on the feature.

Select Calls from iPhone.
If you don’t see this option, make sure your Mac meets all of the requirements, then open FaceTime settings again.
If an Upgrade to Wi-Fi Calling button appears, click it, then follow the onscreen instructions.
This button appears if your carrier supports Wi-Fi Calling when your iPhone is turned off or is on a different Wi-Fi network.
If you’re asked to confirm your address for emergency services, click Update Emergency Address. (If you make an emergency call that uses Wi-Fi instead of cellular, the address you provide here helps emergency services locate you.) See the Apple Support article Make a call with Wi-Fi Calling.
