Calls for all destinations. I have found the best ways for a cheap phone call. You don't need to search anymore. I update the page as often as I find more links to cheap phone services. For business and private use.
Companies can save a lot of money using calling cards.
Let your children always have a calling card to reach you. Order your phone card before your trip. Some phone cards are best for domestic calls, some for long distance calls. The best choice also depends on the length of the phone conversation. Often a combination of two or more calling cards is the best.
