SparkPhone allows you to cheaply and easily make international phone calls on your iPhone. No more confusing calling card numbers and PINs to remember. Our rates are often much cheaper than your carrier's international dialing plan.

SparkPhone allows you to make calls directly from your address book. You can also add favorite contacts, for people you frequently call.

You purchase credits from within the app, using In App Purchase — so it's easy to quickly add more calling credits.
