International Calling Cards

International calling cards are credit cards that are used to pay for telephone usage. Users usually have two choices for using a calling card. One is a pre-payment type, where the buyer purchases a card that specifies a specific amount of funds or a specific amount of time. The other main type of calling card is one that has an account number and a PIN that is connected to a telephone billing system and tied to a cell phone or land line.

Calling cards are especially popular with making a call to Canada or to call UK from USA. But it is also just as popular to phone Korea or making calls to Iraq.
