CallSky Reviews — Discover what people think of this product.

CallSky is an iOS app that lets you make international calls to regular phone numbers in over 180 countries. You buy credits through the app ($4, $8, or $16 packages) and use them to call landlines and cell phones at rates starting from just $0.01 per minute. The person you're calling doesn't need the app or internet - it rings on their regular phone like any normal call.
