[This is a Sponsored Post] I don't know much about calling cards; but wish I did. Frankly it excites me to be able to talk to people anywhere in the world clearly and cheaply. With Pingo's prepaid calling card service you could save up to 90% on international calls. For example, my cousin lives in China, so check out Pingo's China calling card rates, or just get some information about how it all works. Its something to do with getting a toll free card, and inserting the number you require. I might just call the US and find out how the Superbowl is going... Indianapolis Colts 6-7 Chicago Bears.
