What IS callback service?
Callback service allows you to call anywhere in the world FROM Costa Rica at extremely reduced rates. A simple way to view this is that you are actually making a conference call from the USA at low USA calling rates. You request this conference call over the Internet. You enter your login and password and the phone number you wish to call. TWO calls are then made. The first is to YOU here in Costa Rica. The second is to the person you are calling. The two are then conferenced together by computer. In essence, you are paying low US rates to make the call.
