**Why Telvio — What We Do Differently, and What We Do Not Do** > Per-second billing, no connection fee, credit that never expires, and no account at all. The four decisions behind Telvio, and an honest list of what it cannot do. Source: https://telvio.app/why-telvio/ · updated: 2026-09-04 1. [Home](https://telvio.app/) 2. Why Telvio Why Telvio # Four decisions, and the things they cost you Every calling app claims to be cheap. This page is about the four design decisions that decide whether that is true for the way *you* call — and about the five things Telvio deliberately cannot do. - From $0.03 a minute - 41 destinations - No account, ever In one paragraph Telvio places outgoing calls to ordinary landline and mobile numbers over WiFi or mobile data. It bills **per second** with **no connection fee**, the credit you buy **never expires**, and it works **without an account** — no name, no email address, no phone number, nothing to sign up for. Rates start at $0.03 a minute across 41 destinations, published in full and derived from the carrier's own price sheet rather than typed by hand. It cannot receive calls or text messages, cannot give you a phone number, and cannot reach emergency services. Those are not gaps waiting to be filled; they follow from what the product is, and they are listed in full further down. The part nobody compares ## The headline rate is not what decides the bill. Rounding and a per-call fee decide it. Calls a week 12 Typical call length 95s - Per second, no fee $2.47 How Telvio bills. You pay for the seconds you talked. - Rounded to the minute $3.12 Same rate. Every call rounded up to a whole minute. - Rounded, plus a call fee $5.66 Same rate, rounded, plus $0.049 for connecting each call. At **52** calls a month of **95** seconds each, the two models on the right cost **$3.20** more than the one on the left — at exactly the same per-minute rate. *A month of calling at $0.03 a minute under three billing models. The per-call fee of $0.049 is Skype's published connection charge to US, UK, India and Mexico landlines, recorded in March 2026. Free to reuse with a link to this page.* ## 1. Per second, from the moment somebody answers Most of this industry bills per minute and rounds up. Under that model a 35-second call is billed as sixty seconds and a five-second wrong number is billed as a full minute. The per-minute rate you compare between services is identical in both models; what you actually pay is not. How much that matters depends entirely on how you call. On a forty-minute call, one rounding is noise. On the calls most people actually make to family — a minute and a half, several times a week — rounding is a surcharge of twenty to forty per cent that never appears in any comparison, because the number everybody compares is the one that has not changed. Ringing is free, and billing starts when the call is answered. That is worth saying explicitly because it is the other half of the same decision: a call that rang for forty seconds and was never picked up costs nothing at all. ## 2. No connection fee, which is the charge that hides best A connection fee is a fixed amount added to every call regardless of length. It is the single most effective way to make a headline rate look competitive while the bill behaves otherwise, because it is proportionally largest on exactly the short calls that rounding also punishes hardest. It is not a hypothetical practice. In the competitor research behind our [comparison matrix](https://telvio.app/vs/), carried out in March 2026, Skype published a connection charge of $0.049 per call to landlines in the United States, the United Kingdom, India and Mexico, and $0.089 to many mobile destinations. Others in the same set charge a per-call setup fee or a surcharge on particular access routes. Each of those figures is quoted from the service's own published material and dated on the page that uses it. Telvio charges none. There is no per-call fee, no minimum duration, no monthly charge and no inactivity deduction. The complete list of what you pay is: the destination's rate, multiplied by the seconds you were connected. ## 3. Credit that does not expire Prepaid credit that expires is a quiet transfer from the customer to the company, and it is common. In the same March 2026 research, several well-known services documented credit that lapses after a period of inactivity, and one of them — Skype — published a 180-day inactivity rule. A balance you bought and did not spend fast enough simply stops being yours. Telvio credit has no expiry, no inactivity clock and no monthly deduction. Buy the $1.99 pack, call once, come back in a year and the remainder is still there. This is also why the honest advice for a destination you have not called before is to buy the smallest pack: there is no penalty for topping up later and no reward for committing now. The same decision explains the absence of a subscription. There is no plan to choose, no minutes bundle to use up before it renews, and nothing to cancel. If you find a recurring charge on a statement, it is not from this app. ## 4. No account, which changes what can go wrong You do not register, and there is nothing to register with. No name, no email address, no phone number, no password and no social login. The app generates a random installation identifier that holds your balance, and that is the whole of your relationship with us. The immediate benefit is that you can install the app and make a call in under a minute, with a free trial minute so you can hear the line before spending anything. The larger benefit is structural: **a company that never collected your details cannot lose them.** There is no user database to breach, no email list to leak or sell, no password to reuse, and no marketing consent to have quietly assumed. Payment runs through Apple and Google, so we never see a card number either. There is a real cost to this, and it is worth being straight about. Because we hold nothing that identifies you, we cannot find your records from a name or an email address — to exercise a privacy right or to move a balance to a new phone, you need the installation ID from the app's settings screen. Lose it and we may genuinely be unable to identify your data. That is the price of not being able to identify you, and we think it is the right trade, but it is a trade. ## The price on the page is the price the app bills This one is invisible from the outside and it is the decision we would defend hardest. Every rate on this website is derived from the carrier's own price sheet at build time, through the same code path the app uses to bill. No price is typed into a page by a person. The reason is a failure we have already lived through. When our carrier changed in August 2026, the entire price sheet moved: the United Kingdom went from the most expensive destination on the site to the cheapest, and India went the other way. Every rate updated automatically. What did not update, because a person had written it, was the prose around the numbers — sentences naming a country that used to be cheap. Those sentences were wrong the moment the account switched, and nothing detected it. So the copy on this site now names the *shape* of the price sheet rather than a country: “from $0.03 a minute” and “41 destinations” are computed on every build, and the build fails if a page ships an unsubstituted placeholder. It is an unglamorous piece of engineering and it is the reason you can trust a number on this site to match what the app charges. ## What Telvio is not This section is here because the alternative — letting you discover these after you have paid — is how a cheap product produces angry customers. Every item is permanent. - **It cannot receive calls.** Telvio places outgoing calls only and assigns you no number of your own. Everyone you ring sees the app's number, [(434) 280-0044](https://telvio.app/caller-id/1-434-280-0044/), and cannot call it back. - **It cannot send or receive text messages.** There is no SMS capability at all, which also means it cannot receive a verification code from a bank or a website. - **It cannot reach emergency services.** An internet call carries no verified location, so an emergency operator would not know where to send help. Use your phone's own dialler — see [emergency calls](https://telvio.app/legal/emergency-calls/). - **It does not reach everywhere.** There are 41 destinations with a route and a published price. Where there is no route, the app declines rather than connecting at a price it cannot promise. - **It is not a messenger.** No chat, no video, no groups, no app-to-app calling. It dials telephone numbers, and that is the entire product. - **It is not a SIM or a mobile plan.** It uses your existing data connection. Your own number, your own operator and your own plan are unaffected. ## Who is behind it Telvio is published by **Vast Flow, LLP**, which is the company named on the App Store and Google Play listings, on the [privacy policy](https://telvio.app/privacy/) as data controller, and on the [terms of service](https://telvio.app/terms/). Calls are carried by a licensed telecommunications carrier, named in the privacy policy along with every other processor that touches your data. The outbound number every call displays is published on [its own page](https://telvio.app/caller-id/), with the company that holds it named on it. That is unusual in this market and it is deliberate: the alternative is letting a crowdsourced spam board write the first thing anybody learns about the company. Everything a serious telecommunications business is expected to publish is published, at stable URLs, dated: [the emergency call limitation](https://telvio.app/legal/emergency-calls/), [what may not be done with the service](https://telvio.app/legal/acceptable-use/), [how to report an abusive call](https://telvio.app/legal/report-a-call/), [how a lawful request is handled](https://telvio.app/legal/law-enforcement/), [how to report a vulnerability](https://telvio.app/legal/security/) and [what this website stores](https://telvio.app/legal/cookies/). The [trust centre](https://telvio.app/legal/) is the index. ## Who this is for, and who it is not for It is for somebody with people to call in another country and no wish to buy a plan for it: a worker calling home, a family split across borders, a traveller who needs to reach a hotel or a bank, somebody whose relatives do not have — or will not install — a messaging app. The common thread is calling an ordinary telephone number, often briefly, often to someone who is not going to install anything. It is not for you if you need a number people can call you on, if you need SMS, if you want video or group calls, or if the people you call are already reachable on a messenger you both use. In that last case a messenger is free and this is not, and no amount of per-second billing beats zero. [The comparison matrix](https://telvio.app/vs/) lays out which of twenty-seven services can dial a real phone number and which cannot, which is the line that decides this. If you are somewhere in between, the free minute exists precisely for that. Install, call the number you actually care about, listen. It costs nothing and it needs no account, which means the decision is yours to make with evidence rather than with marketing. ## Bottom line Four decisions: per-second billing, no connection fee, credit that never expires, and no account. Together they mean the per-minute rate you compare is the amount you actually pay, which is not true of most of this market. Rates start at $0.03 a minute across 41 destinations, published in full and derived from the carrier's price sheet rather than written by hand. It cannot receive calls or texts, cannot give you a number, cannot reach emergency services, and is not a messenger. Those limits are permanent, and knowing them before you pay is the point of this page. ## Frequently asked questions What makes Telvio different from other international calling apps? Four things: billing per second instead of rounding up to the minute, no connection fee on any call, credit that never expires, and no account of any kind. Together they mean the headline per-minute rate is what you actually pay. Does Telvio require registration? No. There is no account, no name, no email address, no phone number and no password. The app generates an anonymous installation identifier that holds your credit balance, and that is the entire relationship. Does Telvio charge a connection fee? No. There is no per-call fee, no minimum duration, no monthly charge and no inactivity deduction. The total cost of a call is the destination's rate multiplied by the seconds you were connected. Does Telvio credit expire? No. There is no expiry date and no inactivity clock, so a balance you bought and did not use remains available. Several well-known calling services void unused credit after a period of inactivity; this one does not. How cheap is Telvio? Rates start at $0.03 a minute and vary by destination across 41 countries and territories. Every rate is published on the rates page and is derived from the carrier's own price sheet at build time rather than typed by hand. Can I receive calls or texts on Telvio? No. Telvio places outgoing calls only, assigns no phone number, and has no SMS capability in either direction. Everyone you call sees the app's own outbound number and cannot ring it back. Can Telvio call emergency services? No, and this is permanent by design. An internet call carries no verified location, so an emergency operator could not be told where to send help. Use your phone's built-in dialler, which reaches emergency services without credit or a data connection. Is Telvio a replacement for WhatsApp or Signal? No, they solve different problems. Messengers call other installs of the same app for free and cannot dial an ordinary telephone number. Telvio dials telephone numbers and does nothing else, which is what makes it useful for reaching people who will not install anything. ## Start calling worldwide Download Telvio free.
