According to recent industry reports, VoIP services like Viber have captured over 30% of the global calling market by 2025, driven by affordability and accessibility. For expatriates, remote workers, and global teams, Viber’s integration of voice, video, and messaging in one app streamlines workflows, making it a preferred choice for how to make international calls using Viber.
The Mechanics of Viber Out for Global Dialing

This hybrid model supports calls to over 200 countries, with rates as low as $0.01 per minute to popular destinations like the United States or India. To initiate, users purchase Viber Out credits or opt for monthly plans, which can be tailored to specific countries or regions. This flexibility ensures that whether you’re calling a loved one in Europe or a client in Asia, the process remains straightforward and economical.

For recurring needs, explore subscription plans under “Subscriptions.” These range from $4.99 monthly for unlimited calls to select countries, ideal for frequent dialers. Rates vary by destination—check the in-app rate calculator for precision. Pro tip: Enable auto-recharge to avoid interruptions during pivotal conversations.

Enter the full international number in the format +[country code][area code][number], e.g., +44 20 1234 5678 for a London landline. If calling a Viber user, the app prioritizes free VoIP; otherwise, it seamlessly switches to Viber Out.
On desktop, the process mirrors mobile: launch Viber, click the phone icon, and input the number. For video calls, toggle the camera option post-connection. Audio quality defaults to HD, but you can adjust settings in “Account” > “Calls” for data conservation.
In real-world scenarios, this method shines during holidays. Imagine surprising a relative in Australia with a video call—Viber’s low-latency ensures natural interaction, far superior to grainy alternatives.
