Organize your Phone Cards with Calling Card Apps for iPhone

There are a number of iPhone apps are developed to help users organize their calling card information. So instead of carrying around a bunch of cards and a list of PIN codes, you can store that information on an iPhone app so that it's always at your fingertips.

One popular calling card app for iPhone is simply named Calling Card Organizer. This app is available for $4.99 in the App Store and provides you with a way to input calling card information as well as PINs and passwords. You can also associate certain contacts with certain phone cards and let the app keep track of which card needs to be used when you call a certain contact. The app manages a lot of the fiddly number punching for you by taking care of gateway numbers and pins.

Another option is World Access Auto-Dialer, which is an iPhone app created by CallingCards.com. The app automates dialing of local access numbers without having to enter card numbers or PINs. World Access does not allow you to use Wi-Fi to make calls, however, and using the app requires purchasing a compatible card from CallingCards.com.
