Callback System

To allow our clients to make making low-cost international calls, we have implemented a callback system. To use the callback service, a subscriber has to call an allocated number first (see below), and wait for a return call. After receiving this (within a few seconds), the recipient picks up the phone and dials the required number. This system allows the subscriber to receive calls from an overseas country, where call rates are lower in comparison.

Please refer to the following allocated numbers to take advantage of the callback feature:
