What is Telvio?
Telvio is a mobile VoIP application available on iOS and Android that lets users make international phone calls to landlines and mobile phones in over 200 countries. Calls travel over WiFi or mobile data instead of your carrier's cellular network, which reduces costs by up to 98% compared to carrier roaming.
No registration or account creation is required. Download the app and start calling immediately. Minutes are purchased as one-time packages starting at $1.99, never expire, and billing is calculated per second with no connection fees.
Telvio uses Voice over Internet Protocol (VoIP) technology to connect callers to real phone numbers. The person receiving the call answers their regular phone — they do not need any app, special equipment, or internet connection.

Frequently asked questions
How does Telvio work?
Telvio routes your calls over WiFi or mobile data instead of your carrier’s cellular network. You dial a real phone number, and the person on the other end answers their regular phone. They don’t need the app.
Do I need to create an account?
No. Download, open, dial. There is no registration, no email, no password. You can start calling within seconds of installing the app.
What does the free minute include?
Every new install gets one free minute to any country. It works exactly like a paid minute — full quality, any destination. Use it to test the call quality before you buy.
Do purchased minutes expire?
No. Your minutes never expire. Buy them now, use them whenever you need them. No monthly fees, no subscriptions, no surprises.
Can I call landlines and mobile phones?
Yes. Telvio calls real phone numbers — landlines, mobile phones, office lines. The person you’re calling doesn’t need an app or even an internet connection.
How much does it cost to call different countries?
Rates vary by country. Calls to the United States start at $0.02 per minute, India at $0.08 per minute, UK mobiles at $0.08 per minute. Most European landlines cost $0.02 per minute. Check the full rates page for your destination.
Is Telvio safe to use?
Yes. Telvio processes payments through the Apple App Store and Google Play Store, so your payment information is never shared with us. Calls are routed through Telnyx, a Tier-1 VoIP carrier with enterprise-grade infrastructure. We do not collect personal data beyond what is technically necessary to connect your call.
What is VoIP?
VoIP stands for Voice over Internet Protocol. It is the technology that allows phone calls to be made over the internet instead of through traditional telephone lines. When you use Telvio, your voice is converted into data packets and transmitted over WiFi or mobile data to reach the person you are calling. The result is the same as a regular phone call, but at a fraction of the cost.
Does the other person need Telvio installed?
No. Telvio calls real phone numbers — landlines, mobile phones, and office lines. The person you are calling answers their regular phone. They do not need any app, internet connection, or special equipment.
What internet speed do I need?
Telvio works well on most connections. A stable connection with at least 100 kbps upload and download speed is sufficient for clear calls. This includes most WiFi networks, 4G, and 5G connections. Hotel WiFi, airport WiFi, and coffee shop networks typically work fine.
Which countries can I call with Telvio?
Telvio covers over 200 countries and territories. You can call landlines and mobile phones in the United States, United Kingdom, Germany, France, India, Canada, Australia, Brazil, Mexico, Japan, and many more. Check the full rates page for a complete list of destinations and per-minute pricing.
How is Telvio different from WhatsApp or Skype calls?
WhatsApp and similar apps only allow free calls between users of the same app — both sides need the app installed. Telvio calls real phone numbers, so the person you call just picks up their regular phone. Unlike Skype, Telvio requires no account registration and your purchased minutes never expire.
What our users say
I call my parents in Munich every week. With my old carrier it was costing me $40 a month in roaming. Telvio cut that to about $2. The quality is the same as a normal phone call, sometimes better.
Maria K.
Expat in Germany
I travel for work 3 weeks out of 4. Hotels charge $5 a minute for international calls. I just connect to the WiFi, open Telvio, and call my clients for almost nothing. No account setup, which matters when you're in a rush.
James R.
Frequent traveler
Calling my family in Osaka from the US used to mean buying calling cards that expired before I used them. With Telvio the minutes stay forever and the rates to Japan are really low.
