Because Androids devices come from different manufacturers, there isn't only one way to do this.


In general:


Make calls over Wi-Fi

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.

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.

  1. Open the Phone app .
  2. Tap More And then Settings.
  3. Tap Calls.
  4. Tap Wi-Fi calling.
  5. You'll need to set-up an address for 911 calls.

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


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.
