  1. Dial the Callback Number
    • Sign up and register your phone number, then dial the callback number assigned to your account and then hang up after you hear the welcome prompt.
  2. Receive a Call from Rinboo
    • After you hang up we will call you straight back and ask you to enter the number you want to call.
  3. Make your Call
    • Enter your friend’s international number to connect at our low rates.
