Make calls over Wi-Fi

In some cases, you can call people using a Wi-Fi connection instead of using your mobile network. Not all carriers support calls over Wi-Fi.

Important: You may incur additional charges for making calls over Wi-Fi, so check with your mobile service provider for details.

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

Before you can make calls over Wi-Fi, you’ll need to turn on the feature in your settings. If your carrier doesn’t offer Wi-Fi calling, you can still do so through a voice over IP service.

Option 1: Use a mobile carrier’s Wi-Fi calling

You can use Wi-Fi calling without a service on some carriers, but you’ll need to turn it on.

  1. Open the Phone app phone.
  2. Tap More More And then Settings.
  3. Tap Calls.
  4. Tap Wi-Fi calling. If you don't see this option, it’s because your carrier doesn’t support this feature.

Option 2: Use a VOIP service to make calls over Wi-Fi (SIP)

Some services can make calls over Wi-Fi, such as a voice over IP service. To do so, you 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 Create.
  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.

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" in the notification screen.

When you're not connected to Wi-Fi, your calls will use your mobile network, if you have one.
