App Description
CallSky connects you to real phone numbers in 180+ countries. Landlines and mobiles, through the actual phone network — not an internet-to-internet gimmick. The person you're calling doesn't need an app or even WiFi.
Rates start at $0.02/minute. That's up to 90% less than what your carrier charges.
WHY CALLSKY EXISTS
International calls shouldn't cost a fortune. And when you call your mom in another country, she should see your name on her phone — not "Unknown Caller." We built CallSky because existing options were either too expensive, too unreliable, or both.
WHAT YOU GET
- Rates from $0.02/min across 180+ countries. You see the exact cost before you dial.
- Your verified number shows as caller ID. People actually pick up when they recognize who's calling.
- Two providers behind the scenes. If one path fails, CallSky switches to another and shows you the rate before connecting.
- No subscriptions. Buy credits when you need them, use them whenever.
WHO USES CALLSKY
- Parents calling family overseas every week without dreading the phone bill
- Business owners reaching international clients who need to see a real caller ID
- Students abroad calling home
- Travelers who'd rather not pay roaming rates
- Anyone calling banks, embassies, or government offices in another country
- Former Skype users who need a replacement for international calls
PLEASE NOTE
- Outgoing calls only — CallSky makes calls, it doesn't receive them
- Not for emergencies — always use your phone's native dialer for 911, 999, or 112
- Needs WiFi or mobile data to place calls
HOW IT WORKS
1. Sign in with Google, Apple, or email
2. Verify your phone number for caller ID (optional but worth it)
3. Buy credits — pay as you go
4. Dial the number, check the rate, and call
UNDER THE HOOD
- Dual-provider routing picks the best path for each call
- Automatic failover if the first route drops — you approve the backup rate first
- 99.9% uptime
No monthly fees. No contracts. No hidden charges.
