CallSky: International Calling Made Simple, Affordable & Reliable
CallSky makes outgoing calls to real phone numbers worldwide. Unlike traditional VoIP apps, CallSky connects directly to the public telephone network (PSTN), so your calls reach landlines and mobile phones just like a regular phone call. This is not a two-way internet calling app — it's a simple, affordable way to call anyone in the world.
Save up to 90% on international calls whilst ensuring your calls always reach their destination. CallSky is the smart international calling app that combines unbeatable rates, verified caller ID, and intelligent routing to keep you connected globally.
THE PROBLEM WE SOLVE
International calls through traditional carriers are expensive and often fail to connect. Your family, clients, and contacts overseas deserve better than dropped calls and surprise phone bills—and you deserve to be recognised when you call.
THE CALLSKY SOLUTION
• Dramatic Cost Savings: Call 180+ countries starting at just $0.01/minute—up to 90% cheaper than traditional carriers
• Verified Caller ID: Use your own verified number so contacts recognise you and answer your calls
• Always-Connected Technology: Intelligent dual-provider routing finds the best path, with transparent rates if backup is needed
• Complete Transparency: See exact per-minute rates before every call, monitor usage in real-time, zero hidden fees
USE CALLSKY WHEN YOU NEED TO:
• Call family and friends abroad regularly without breaking the bank
• Reach international business contacts and have them recognise your number
• Contact overseas institutions (banks, embassies, universities, government offices)
• Stay connected whilst travelling without expensive roaming charges
• Replace costly international calling features from legacy apps like Skype
• Manage international client relationships with professional caller ID
• Make frequent calls to mobile phones and landlines worldwide
IMPORTANT: PLEASE NOTE
• Outgoing calls only - CallSky is for making calls, not receiving them
• Emergency calls (999, 112, etc.) - Always use your device's native phone app for emergencies
• Requires internet - CallSky needs WiFi or mobile data to place calls
HOW IT WORKS
1. Download and sign in (Google, Apple, or email)
2. Verify your phone number for caller ID (optional but recommended)
3. Add credits via secure in-app purchase (pay-as-you-go, no subscriptions)
4. Dial any international number - see the rate before connecting
5. Make crystal-clear calls with your verified number displayed

What's New in Version 2.0.7
Fixed an issue where calls to Italy, Vatican City, San Marino, Argentina, and Ivory Coast were incorrectly rejected as "invalid number". These countries require keeping the leading zero in certain phone numbers, which is now handled correctly.
