Start by downloading and installing the Google Hangouts app (Apple App Store, Google Play Store) on your phone or tablet. When opened, the app will show you a list of recent conversations.
To start a call; tap on the + (plus) icon in the bottom right and choose New video call from the options.
You can select a person from the list of contacts by searching for their name, phone number, or email address. This list should include all of your phone and email contacts. If you don’t see your love-one, please first add them as a contact. Start the call by tapping on the green video icon in the top right.
Success!
