This minimizes your exposure to theft by denying thieves the ability to reach 900 numbers or overseas locations. Pricing Calling cards cost more to administer than standard long distance service, and thus cost more. However, many cards are radically overpriced. Cards with an access charge typically bill 20 to 35 per minute, plus an access surcharge of 35 to 65 . Cards without an access charge typically bill 30 to 40 per minute.
Calls also vary in cost depending on the time of day and the call rounding used with the card.
Most cards bill a minimum 30 seconds per call and round calls to the nearest full minute. Buying Tips Expand your range of choices Using a calling card issued by your long distance carrier is not always the cheapest option. Even when you factor in volume discounts, cards from other carriers are often much less expensive. Local cards Travelers who make most calls within one area code should consider a calling card offered by the local telephone company. These carriers usually provide better rates for calls placed in the local region.
