You can call abroad using both Call Back and Call Out. On the ‘Preparing call’ screen you will see the price per minute cost of the call to the destination you want to contact. 

It can be cheaper to call abroad with Infocaller app. Compare our rates to your carrier’s. Calls are made through the digital GSM network just like traditional calls, ensuring the highest quality to all destinations.

It is not necessary for the call receiver to have the Infocaller App -only their regular phone to receive a call as any other.
