Prepaid international calling cards offer you a wide range of advantages on international calls:
- They usually offer the lowest rates available - you can save up to 90% of the cost of a normal call.
- You can use them from every phone (work, home, mobile and public phones)
- If you use a toll-free number, you can call from work or a friend's phone without them being charged for the call.
- It's easy to control your spending and avoid the "bad surprise" of an astronomical monthly phone bill.
Card providers offer such cheap calls because they buy high quantities of international minutes at large discounts.
