About this app
Telvio makes international calls simple: open the app, dial any landline or mobile number in 90+ countries, and talk over WiFi or mobile data. No SIM swap, no roaming, no account, no contract - and your first minute is on the house.
CALL ANY PHONE, NOT JUST APP USERS
Telvio places real international calls to real phone numbers. The person you call does not need Telvio, an app, or the internet - a regular landline or mobile phone rings anywhere in the world.
PAY ONLY FOR THE SECONDS YOU TALK
Per-second billing with no connection fee. Buy a small credit pack when you need it - your credit never expires, so an unused balance simply waits for your next international call.
NO ROAMING, NO SIM SWAP
Calls travel over the internet, so hotel WiFi or a local data plan is enough. Skip roaming charges and plastic calling cards when you travel.
NO ACCOUNT, NO SIGN-UP
There is no registration, password, or profile. Open the app and dial - Telvio sets up an anonymous balance for you automatically.
CLEAR RATES BEFORE YOU DIAL
See the per-minute rate for every destination before the call starts, and watch your balance in real time while you talk.
MADE FOR TRAVELERS, EXPATS, AND FAMILIES ABROAD
Call parents on their home landline, reach a hotel or embassy overseas, confirm a booking, or stay close to family in the Philippines, India, Vietnam, Brazil, Mexico, and beyond. International calling that works the moment you land.
CLEAR CALL QUALITY
Telvio routes calls through premium carrier lines, not peer-to-peer connections, for reliable quality to 90+ destinations.
Note: Telvio is for outgoing calls only. It does not provide a phone number for incoming calls, and emergency numbers are not supported.
