What's New in International Calling

2.7.0

October 30, 2026

- Near the end of your credit, the call screen now shows the minutes left, then counts down the last minute. - When your credit runs out during a call, you'll now hear a short message in the app's language before the call ends. - If a call ends because your credit ran out, the end-of-call screen now tells you, with your remaining balance and an Add Credit button. - Calls to Spain connect Monday to Friday, 9 AM to 9 PM, and Saturday, 10 AM to 6 PM, local time in Spain, except on Spanish public holidays. Outside those hours, the dialer now shows when calls open again, and you can ask for an exception if you're calling family or friends. - A friendly cloud now welcomes you when the app opens and guides new users through sign-up to their first call. - Signing out on your iPhone no longer signs you out on your other devices.

User reviews

You can‘t pay with credit card only through App store

That is totally unacceptable

Response from developer

Hi Jason, Thank you for your review. We understand your frustration with the payment options, but this is actually outside our control — Apple requires all iOS apps to use In-App Purchases for digital goods and does not allow developers to add direct credit card processing as an alternative. We did look into offering this and it's simply not permitted on the App Store. A 1-star rating for an Apple platform policy is a double punishment for us, because there is genuinely nothing we can do to change it. We'd be very grateful if you'd reconsider your rating, or update your review to focus on the app itself — call quality, rates, ease of use, support — anything we can actually improve. If there's something about CallSky specifically that didn't work for you, please email us at support@venuscloud.com and we'll personally look into it. Thank you, CallSky Team

doesn’t work , I tried to call 3 times and Nothing. Garbage

Do not buy this junk.

Response from developer

We're sorry your international calling experience didn't go as expected. Our app handles thousands of international calls daily and we'd love to get yours working too. Please reach out to us at support@venuscloud.com so we can look into it right away.

Just like calling down the street

The call was clearer than some that I make to folks in country, let alone in the same city. Very pleased with the billing rate and quality of call I experienced calling Ireland.

Response from developer

Thanks for the kind words! Glad the international calling quality to Ireland came through so clearly. That's always the goal with our international calling app. Appreciate you taking the time to write this.

Love this app !

Fantastic service, connectivity was Cristal clear and the app is so easy and fast to use.

Response from developer

Thank you so much for the kind words! We're really happy to hear the call quality and experience have been great for you. Reviews like yours make all the hard work worthwhile. Happy calling!

Good app

Great app to replace Skype, 10 out of 10.
