Do I need to download an app to use Kinvo?

No. Kinvo works entirely in your browser using WebRTC technology. Just sign up, add credits, and start calling. It works on Chrome, Firefox, Safari, and Edge on any device with a microphone.

How does the Kinvo credit system work?

Buy credits in preset amounts ($5, $10, $20, $50, or $100) or a custom amount. Each call deducts credits based on the per-minute rate for that country plus a $0.05 connection fee (only charged when the call is answered). Credits never expire. Larger packs include bonus credits: $20 pack gets +$1, $50 gets +$5, $100 gets +$15.

What countries can I call with Kinvo?

Kinvo supports calls to over 150 countries including the US, UK, Canada, Australia, India, Germany, France, Japan, Brazil, Mexico, Philippines, and most of Europe, Asia, Africa, and South America. Both landline and mobile numbers are supported.

Is Kinvo call quality good?

Yes. Kinvo uses WebRTC with HD voice codecs for crystal clear audio. All calls are encrypted end-to-end. Call quality is typically better than traditional phone calls, with real-time quality indicators showing latency and packet loss.

Can I use my own phone number as caller ID on Kinvo?

Yes. You can verify your personal phone number through Kinvo's caller ID feature, and recipients will see your real number when you call. You can also purchase virtual phone numbers in the US, UK, Canada, and Australia.

Do Kinvo credits expire?

No. Your credits stay in your account indefinitely until you use them. There are no hidden fees, no monthly minimums, and no expiration dates.

Is Kinvo a good alternative to Skype for international calls?

Yes. Kinvo was built specifically to fill the gap left by Skype's shutdown in May 2025. Like Skype, Kinvo offers affordable international calls with a pay-as-you-go model. Unlike Skype, Kinvo requires no app download — calls are made directly from the browser. Kinvo supports 150+ countries with HD WebRTC voice quality, team accounts, and caller ID verification.

Rates vary by country. Calls to US and UK landlines start from $0.01/min. Mobile rates are typically higher. There is a $0.05 connection fee per call, charged only when the call is answered. You can check exact rates for any country before you dial. Every new account gets a free 1-minute test call.

How to Choose the Right Browser VoIP Service

For personal international calling: Choose Kinvo or Google Voice (if US-based). Both offer the lowest per-minute rates with no monthly commitment. Kinvo has broader country coverage and credits that never expire.
For teams making international calls: Choose Kinvo (for pay-as-you-go with team wallets) or Zadarma (for full PBX features). Kinvo is simpler; Zadarma is more powerful but more complex.
For enterprise communications: Choose Vonage or DialPad if you need a complete unified communications platform. International calling will be one feature among many.
For maximum features: Choose YadaPhone if you need inbound calls, call recording, or AI transcripts alongside outbound international calling.

Frequently Asked Questions

What is browser-based VoIP?

Browser-based VoIP (Voice over Internet Protocol) is a technology that lets you make phone calls directly from your web browser using WebRTC. Your voice is converted to digital data, sent over the internet, and connected to the traditional phone network at the destination. The recipient's phone rings normally — they cannot tell you are calling from a browser.

Is browser-based calling as good as regular phone calls?

Modern browser-based calling using WebRTC typically provides better audio quality than traditional phone calls. WebRTC uses the Opus codec, which captures a wider frequency range (up to 20 kHz vs. 3.4 kHz for traditional phones), resulting in clearer, more natural-sounding voice. All WebRTC calls are also encrypted end-to-end, which traditional phone calls are not.

Do I need to install anything?

No. Browser-based VoIP services work in your existing browser (Chrome, Firefox, Safari, Edge) without any downloads, plugins, or extensions. You just need a microphone and an internet connection.

Can I call mobile numbers, not just landlines?

Yes. Browser-based VoIP services can call both landlines and mobile numbers. Mobile rates are typically higher than landline rates — for example, calling a UK landline might cost $0.01/min while a UK mobile might cost $0.10/min.

Bottom line: For most people making international calls in 2026, Kinvo offers the best combination of low per-minute rates ($0.01/min), zero monthly fees, credits that never expire, and reliable HD quality with dual-provider infrastructure. YadaPhone is the better choice if you need inbound calls or call recording. Business-focused platforms like Zadarma, Vonage, and DialPad are better suited if you need a complete phone system, not just international calling.
