About this app

Call any phone number in the world — landlines and mobiles — at low per-minute rates. CallSky is a pay-as-you-go international calling app with no monthly fees, no contracts, and no hidden charges.

Skype shut down. CallSky picked up where it left off. If you used Skype to call landlines and mobile phones abroad, CallSky is the closest replacement: simple credit-based calling to 180+ countries with rates starting at $0.01/min.

HOW IT WORKS
1. Sign up with your email
2. Buy credits ($5, $10, or $20)
3. Dial any international number and start talking

Credits never expire. You only pay for the minutes you use.

Ratings and reviews

A great app to make cheap calls to my family's landline overseas. Good call quality and it's been 100% reliable for me.

At first, the app didn't work for me, so I had to use another application and ended up paying twice for the same service. After following the suggested solution, it finally worked, which is why I'm updating my review from one star to three stars. because of the cost and average call quality, I think three stars is a fair rating.
