I want call my PC in Bangladesh. I have iPhone platinum calling card. How can I do it?
If you have the card, access the official website and download the necessary dialer. Once the dialer is installed, input the details from the calling card and dial the number you want. The same thing needs to be done to the PC where you want to call. You can't call to a destination that doesn't meet the base requirements.
