Callback is a calling system that KnowRoaming offers in some countries to offer users a cheaper calling rate. Watch this video to see how Callback works.
How does it work?
When you make a normal call, instead of it connecting directly, the call disconnects after you dial and you receive an incoming call connecting you to the number dialed.
KnowRoaming automatically defaults the calling system to call back in some countries in order to offer the user a better calling rate.
If you are traveling to a specific country, and want to check if call back is available, check the rates in the KnowRoaming App.
