Set up Google Duo
You can use Duo to call your family, friends, and anyone else who uses the app.
Step 1: Install Duo

Step 2: Verify your phone number
- On your Android device, enter your phone number and make sure it's correct.
- Tap Agree.
- Duo will send a code in a one-time SMS message to the number that you entered. (Carrier text-message rates may apply.)
- Enter the code that you received in the text message.
- If you don't receive a text message, tap Resend SMS.
- If you have a cell connection and aren't getting the SMS, request a call by tapping Call me.
- If you continue having problems verifying your phone number, visit the verification troubleshooting article.
To connect your Google Account, tap Agree.
