Yes! The green Talk button with the phone icon (pictured below) will be visible if the Psychic is online and available to take a call. Tap the green Talk button to talk with the Psychic.
If you do not see the green Talk button, the Psychic may be on a call or offline. You can check back later to see if the Psychic is available, choose another Psychic who is available, or select a different type of reading to continue.
