What is Callback?
Posted by Rock V. on 17 December 2014 08:31 AM


This service is very useful when there is no access number in your current location (for example when you are abroad), and fees for internet connection are high.

Not like the Local Numbers service, Rinboo International Callback service is available from any country in the world!

  • Easy access to lowest international rates from any country in the world!
  • Perfect for travelers!
  • Change your callback number at any time.
  • Use it from any phone.
  • Speed dials offer a fast connection.
  • No monthly fees.

Just dial the Callback number then hang up, we won’t answer so you won’t be charged by your operator!

We’ll call you back to connect you to the international number at our low rates.
