In some cases, you can call people over a Wi-Fi connection instead of a mobile carrier. Not all carriers support calls over Wi-Fi.
Before you can make calls over Wi-Fi, you'll need to turn on the feature in your settings.
Turn on Wi-Fi calling
Important: You may incur additional charges for making calls over Wi-Fi, so check with your mobile service provider for details.
Use a mobile carrier’s Wi-Fi calling
- Open the Phone app .
- Tap More Settings.
- Tap Calls.
- Tap Wi-Fi calling. If you don't see this option, it’s because your carrier doesn’t support this feature.
- You can use Wi-Fi calling without a service on some carriers.
- If your carrier doesn't offer Wi-Fi calling, you can still do so through a voice over IP service.
Place a call using Wi-Fi
Once you’ve set up Wi-Fi calling, you can make a call over Wi-Fi just like any other call. When you’re connected to the internet, you’ll see "Internet Call" or "Wi-Fi calling" on the notification screen.
When you're not connected to Wi-Fi, your calls will use your mobile carrier, if you have one.
