In some cases, you can call people over a Wi-Fi connection instead of a mobile operator. Not all operators support calls over Wi-Fi.
Before you can make calls over Wi-Fi, you'll need to turn on the feature in your settings.
Important: Some of these steps only work on Android 6.0 and up. Learn how to check your Android version.
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 operator’s Wi-Fi calling
- Open the Phone app .
- Tap More Settings.
- Tap Calls.
- Tap Wi-Fi calling. If you can't see this option, it will be because your operator doesn’t support this feature.
- You can use Wi-Fi calling without a service on some operators.
- If your operator doesn't offer Wi-Fi calling, you can still use this feature through a voice-over IP service.
Make a call using Wi-Fi
Once you’ve set up Wi-Fi calling, you can make a call over Wi-Fi just as you would 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 operator, if you have one.
