Available for sale at countless retailers around, pre-paid calling cards offer a cheaper way of calling abroad from your smartphone, but they do involve dialling insanely long numbers, and of course having the card number with you at all times. Which is where Smart Calling Cards for Windows Phone comes in.

The app will keep a track of your calling cards, storing the account number, the dial-in numbers, and PIN numbers to make. Once those details are in the app, you can choose any of the contacts in the People Hub through the app, and Smart Calling Cards will put together the numbers, and pass them to the dialler app.

While it's not dialling directly from the People Hub, it's a good solution that many should find useful.
