BubblyPhone vs Viber: International Calling Rates Compared (2026)
Table of Contents
BubblyPhone vs Viber for international calls — which one actually gives you better rates and call quality? If you regularly call landlines or mobiles abroad, the price difference between these two services can add up fast.
We tested both services across 15 countries to compare real-world costs, call quality, and ease of use. Here is what we found.
How BubblyPhone and Viber Out Compare
Both services let you call regular phone numbers (landlines and mobiles) anywhere in the world. But they work differently under the hood.
BubblyPhone is a browser-based VoIP service — no app download required. You pay per minute with no subscription, and calls connect through WebRTC directly in your browser. Viber Out is the paid calling feature inside the Viber messaging app. You buy credit or a monthly plan to call non-Viber numbers.
International Calling Rates: Side by Side
Here is how per-minute rates compare for popular international destinations. Viber Out rates vary by plan; we show their pay-as-you-go credit rates.
Call Quality Comparison
Both services use VoIP technology, but the experience differs noticeably.
BubblyPhone routes calls through Telnyx's global network with dedicated infrastructure in 30+ countries. We measured an average latency of 45ms on US-to-India calls, with clear audio and minimal jitter.
Viber Out quality depends heavily on your internet connection and Viber's routing. In our tests, call quality was acceptable but we noticed occasional audio delays (120-180ms latency) and compression artefacts, especially on calls to mobile numbers in Africa and Southeast Asia.

When to Choose Viber Out
- You already use Viber daily for messaging and video calls
- You call one specific country very frequently (monthly plan can save money)
- You want free Viber-to-Viber calls bundled with paid outbound calling
- You prefer managing everything in one app
When to Choose BubblyPhone
- You call multiple countries and want the lowest per-minute rates
- You don't want to download another app
- You need to make international calls from a work computer or shared device
- You want a US caller ID number included at no extra cost
- You prefer pay-as-you-go with no subscription commitment
The Bottom Line
For most people calling abroad, BubblyPhone offers lower rates across the majority of destinations — especially mobiles in India, Mexico, Nigeria, and Pakistan where savings range from 50-75%.
Viber Out makes sense if you're already embedded in the Viber ecosystem and primarily call one country. But if you call family or business contacts in multiple countries, BubblyPhone's browser-based approach with transparent per-minute pricing is hard to beat.
