Question 1

Do I need to download an app to use Kinvo?

Accepted Answer

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.

Question 2

How does the Kinvo credit system work?

Accepted Answer

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.

Question 3

What countries can I call with Kinvo?

Accepted Answer

Kinvo supports calls to over 220 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.

Question 4

Is Kinvo call quality good?

Accepted Answer

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.

Question 5

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

Rates vary by country. Calls to US and UK landlines start from $0.03/min. Mobile rates are typically higher. There is a $0.05 connection fee per call, charged only when the call is answered.

Kinvo is one of the most affordable browser-based international calling services.

The pay-as-you-go model means you only pay for the minutes you use.
