Vyke Callback is a quick and simple way to access low cost international calling from virtually any phone worldwide.

The Vyke system captures the calling line identification and calls the user back. Once connected, the user enters the destination phone number and is connected.

Vyke Callback enjoys a high degree of market familiarity and can be used from virtually any phone, avoiding any compatibility issues in areas where access to the Internet is limited or mobile handset technology is still under development.
