Calling on the Cards

Prepaid calling cards are increasingly popular. In Singapore alone, more than 30 companies provide over 100 types of prepaid international calling cards. The cards' appeal is that they usually offer much less expensive rates than other types of services. But they aren't perfect. Here are some things to keep in mind when using prepaid calling cards.

1. Though call rates are often low, some cards have hidden charges like connection fees. Read the fine print before buying.

2. Beware if you need a log of your calls for business or personal reasons - calling cards don't provide any records.

3. Before you buy, check for hidden charges, such as connection fees.

4. Some cards only reach certain areas.

5. Many cards expire 90 days after they are first activated.

6. Make sure you can use the card where you want. Some cards can't be used in hotel rooms. Others are blocked in private residences.
