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.

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.

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.
