## What is International Calling?

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.

### 1/5 — You can‘t pay with credit card only through App store

*2026-03-26*

That is totally unacceptable

**Developer response:** 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

### 5/5 — Just like calling down the street

*2026-02-26*

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.

**Developer response:** 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.

### 5/5 — Love this app !

*2025-11-06*

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

**Developer response:** 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!

### 5/5 — Good app

*2025-08-22, version 1.1.1*

Great app to replace Skype, 10 out of 10.

### 5/5 — Simple and useful!

*2025-05-14, version 1.0.1*

Handy to have this option given Skype etc no longer do it
