Communication : Calling-Card
Calling Cards you will receive your tickets on the street sometimes, or see advertised in the store on the corner. They are a cheap way for international calls – much cheaper than regular landline phone – and they get more and more popular because more people live and work abroad to choose and international friends.
The way calling cards work? There are mainly two types of cards: free and paid. Free calling card has a high premium on the telephone number that you, and enter the card number and PIN number. Premium rate phone call pays a minute for you to state your choice. Paid with the card number and PIN card, except that you buy at the store together instead of paying a premium to call local rate.
The reason your calls can be so much cheaper than usual when you use a calling card is that they are no longer being routed through the normal phone network. Instead, calling card companies are free to construct their own international telephone networks, often using advances in technology to their advantage.
Most modern calling cards actually route calls over the Internet, which means that an international call in fact becomes only a local call at each end, with the Internet acting as a ‘bridge’ between the two phone networks. This means that the calling card companies can make a lot of money for very little work, while also providing a much cheaper service than usual to the customer.
If you want to cut out the middleman, though, you might consider using a voice-over-IP service on your computer, such as Skype. This allows you to make calls for free over the Internet, and at local rate to landline phones all over the world. While you have to have a computer and Internet access and use a headset instead of a phone, the calls are a lot cheaper than even the cheapest calling card.
