200,000+ international calls connected since launch
CallSky is an international calling app that lets you call landlines and mobile numbers in 180+ countries. It's pay-as-you-go from $0.02 a minute, with no subscription and credits that never expire. The person on the other end just picks up like they would any other call. There's nothing for them to install.
CallSky launched after Skype shut down in May 2025. WhatsApp, Viber, and Line cover app-to-app calls, but none of them reach a regular landline. That's the gap CallSky fills.
No app on the other end
Call any landline or mobile number worldwide. The person you're calling just answers their normal phone. No invitation, no download, no signup. Works for anyone with a phone.
No subscription, no surprises
Pay only for the calls you make. Rates start at $0.02 per minute, shown before you dial. Credits never expire. No monthly fees, no connection charges, no contracts.
Three apps, one account
iOS, Android, or any web browser. Same credit, same call history, same contacts across every device. WiFi or mobile data. No SIM required.
How CallSky works
Three steps. No carrier deals, no SIM swaps, no porting numbers.

Frequently asked questions
The ones that come up most before signing up.
Does the person I’m calling need the app?
No. They answer their normal phone the way they always do. CallSky calls their landline or mobile directly, so there’s nothing for them to install or sign up for.
Does my phone number show on caller ID?
By default, a real US or UK number from a shared CallSky pool that rotates monthly, and you can pick which country it comes from. If you’d rather show your own number, verify it in the app and your usual number appears on their phone instead, so people recognize you and can call you back.
Can I bring my Skype contacts across?
Yes. The iOS and Android apps import contacts directly from your phone. The web app accepts a CSV upload or imports from a Google Sheet. Whatever you bring in lands in your CallSky account and syncs across every device. If you exported your Skype contacts as a CSV before the shutdown, drop the file in and you’re set.
I used to top up Skype Credit. How is CallSky different?
Skype Credit went inactive after 180 days and added a connection fee on top of the per-minute rate. CallSky credits don’t expire, and there’s no connection fee. The rate shown before the call is the full price.
How is the call quality on mobile data?
Good on a stable 4G connection or better. Your end carries the audio over data, so your link is the bottleneck. The person you’re calling is on the regular phone network, so their side is whatever a normal phone call sounds like.
Can I call emergency numbers like 911 or 999?
No. CallSky cannot reach 911, 999, 112, or other local emergency numbers. The service routes calls through international carriers, not local emergency dispatch. For emergencies, use your regular mobile or a landline.
What happens to my credit if I don’t use the app for a while?
Nothing. Whatever’s in your balance is still there when you open the app again, whether that’s next month or next year. There’s no inactivity expiry and no maintenance fee.
