Calling cards have been around for a very long time, they became especially popular in the 90s just before cell phones took over. You can find them in just about any store such as Walgreens or Wal-Mart. Now they even have rechargeable phone cards. These rechargeable cards can be bought and recharged when they run out of time.
Different calling cards allow different amounts of time depending on how much money is on them and where you are planning on calling. Larger amount calling cards will provide you with more talk time and can also have the added benefit of costing less per minute. Cheaper calling cards such as dollar calling cards will get you much less talk time, but if you're in a pinch they can be a lifesaver.
Most people buy phone cars in denominations around $20. These are good if you are planning on making multiple calls. If you make a lot of calls internationally, a larger denomination card is pretty much a requirement. The dollar pone cards are best for quick emergency calls and nothing more.
Even if the dollar phone cards are rechargeable it would be a waste as you would have to recharge after the first use. There is no point in her charging a dollar calling card. If you are planning on getting a rechargeable phone card you might as well start out with one with a decent amount of time on it.
Calling cards can be very useful and can make a good stocking stuffer to friends and family who don't have cell phones. Their best use is making international calls. However, with voice over IP technology, making international calls cheaper, we will probably see calling cards quietly disappear or shrink in popularity in the next decade or two. Also, pay-as-you-go phones are becoming very popular with the youth and as they get older these phones may also provide a viable and popular alternative to calling cards.
