Callback
What is a Callback? A process where you call a given callback service's number, hang up, and are called back by the service. Generally, an automated system asks for a number to call and connects the call for you. You generally pay the callback service for connecting your call.

How is this useful? Callback is a good way to avoid high roaming fees for calling directly. This is most true for phone plans that allow free incoming calls. Often, the rate charged by the callback service for connecting the call is relatively low.
