The Message button means you can send that Psychic an Offline Message.
The cost to send an Offline Message is 5 minutes at the Psychic's listed per minute rate for each message you send. The Psychic will reply to you as soon as possible. If the Psychic does not respond within 24 hours, the system will automatically reimburse the cost of the Offline Message back to your reading account.
The Message button can be found by a Psychic's photo on the All Psychics screen and on the Psychic’s full profile. When you click (or tap) the button, the Offline Message screen ("Send Message" screen in the App) displays.
Clicking/tapping the Begin Your Message button will show the following response and send a text message from "California Psychics" to your mobile number on file.
Once you are in the text message window, you can type your Message and press the send button.
