Make calls with Google Duo

You can make video or audio calls to anyone in your contacts. Learn how you can find and add people to call.

All calls, including international ones, are made through your mobile data plan or a Wi-Fi connection, so you won't use your mobile minutes. If you use your mobile data, charges may apply. 

Make sure you have the latest version of the Duo app and you're running Android 7.0 and up.

Start a video or audio call

1. If you don't already have Duo on your device, install the latest version and set it up.
2. On your Android device, open the Duo app.
3. Choose Video or Audio  .
4. Tap the contact.
5. When done, tap End call .

If you have a Google Home device connected to your Duo account, you can call it from the app: 

1. On your Android device, open the Duo app.
2. At the top of your contact list, tap Call Home.

Duo will call any Google Home device you’re signed in to, like Smart Displays with Google Assistant.

Make calls from other apps

You can make Google Duo calls from other apps.

If your carrier has its own video-calling feature:

• If you and the person you’re calling have the same carrier, the call might use your carrier’s video service.
• If you have different carriers, the call will use Google Duo.

Fix problems with calls

• Make sure you have the latest version of Duo installed.
• Check that you've registered Duo:
  • Verify your phone number.
  • Allow access to your contacts.
• Learn how to stop getting all Duo calls.

Note: If you've connected your phone number to any Google services, you may automatically be registered with other products, like Google Duo.
