Even when you don’t have an Internet connection, you can make VoIP calls with our CallBack service.

How does it work?

When using Callback, our server connects to your phone and then the phone of the person you’re calling. This is done via a telephone network, not Internet.

4 Steps of the Callback Service

  1. You make a request to our server (either with a phone call or over the Internet).
  2. You receive an incoming call and listen to the message: «Wait for connection».
  3. Our server calls to the person you’re trying to reach.
  4. Once the call is answered, you're connected!

Two ways to request a Callback:

  1. The Zadarma website

    Log in to your personal account. Enter the numbers you want to connect and click "Connect". Wait for the call.

  2. WAP

    You can use a direct link to our website and save it to your phone.

  3. Register
