For people that travel to areas where they cannot access the internet or do not have a country access number available for them to use, the only choice to make calls at cheaper rates is using a "callback" service.

With the callback service you dial this number +420-240-200-079. Our system will give you a busy signal when you call this number so you are not charged for the call. Our system will recognize your calling number and then call you back at that number. You will hear a prompt to dial the destination number you want to call.

When you signup for a Diamondcard account you can enter all your phone numbers that you might be using the callback service from. This way our system will recognize your calling number. If our system doesn't recognize your calling number it won't be calling you back. You enter your callback numbers in your Diamondcard administration center. This is where you login with your username and password. Click the LOGIN link at the top of this web page to login to your account.

Callback phone calls are charged at our IP phone rates. These are the lowest rates we have. Our callback rates are cheaper than just about any other company out there that also offers a callback service.

Here is an example. Let's say you are calling the USA from Ukraine. You want to call from your Ukrainian mobile phone. You dial our callback number from your Ukrainian mobile phone. The system calls you back on your Ukrainian mobile phone. You dial the USA phone number you want to call and start talking when you are connected. The IP phone rate for calling you back on your Ukrainian mobile phone is $0.171/min. This is the first leg of the callback call. The IP phone rate for second leg of your callback call is to the USA and that rate is $0.021/min. Both legs are added up and the total for this callback call is $0.191/min.
