Make calls over Wi-Fi

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.

Note: Some of these steps work only 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.

Option 1: Use a mobile operator's Wi-Fi calling

  1. Open the Phone app phone.
  2. Tap More More And then Settings.
  3. Tap Calls.
  4. 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.

Option 2: Use a VoIP service to make calls over Wi-Fi

Some services can make calls over Wi-Fi, such as a voice-over IP (VoIP) service, for example. To use these services, you'll need to add a 'session initiation protocol' (or SIP) account to your phone.

  1. Open the Phone app phone.
  2. Tap More More And then Settings.
  3. Tap Calls And then Calling accounts And then SIP accounts.
  4. Tap Create Insert.
  5. Enter the username, password and server of your new SIP account.
    Tip: To change your port number, nickname or other fields, tap Optional settings.
  6. Tap Save.

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.
