Prepaid cards are easy to use.
Your calls are charged against the card until the value is depleted. So you don't want to use these cards for just any call. When to use one Use a prepaid card when you would normally use your telephone credit card, but only when the access fee makes your credit card call cost more than the prepaid call.

Where to get one You can purchase prepaid cards at stationery shops, electronics stores, even at your local corner deli.
