Does it reach ordinary phone numbers. What is the billing increment. Is there a connection fee. Does credit expire. What does registration demand. Those five are chosen because they are checkable and because they decide the outcome. Call quality is the property everyone asks about and the one no comparison can honestly generalise: voice routing is per-destination, and a service that sounds excellent to Mexico can sound poor to a rural line in a market where the terminating operator runs old equipment. Where a page has something concrete to say about quality it says it and names the corridor; where it does not, it says nothing rather than inventing a verdict. Price is compared where both sides publish a figure for the same country. Most services do not publish per-country pricing for most countries, so most comparisons carry fewer price rows than a reader would like. That is the honest state of the market rather than a gap in the research. ## The distinction most comparisons blur There are two different products both called "calling apps", and comparing across the line produces nonsense. **App-to-app services** — WhatsApp, Signal, Telegram, FaceTime, Discord — carry voice between people who installed the same application. They are free, they are usually excellent, and they cannot reach a telephone number. Their real cost is a requirement on the other person: a smartphone, an internet connection, and the same app. **VoIP-to-PSTN services** — Skype, Viber Out, Rebtel, Talk360, Telvio, calling cards — connect to the public telephone network. The person you call needs nothing at all; the call arrives as an ordinary phone call on any phone. They cost money because the operator at the far end charges to accept the call. A comparison of a free app-to-app service against a paid PSTN service is not a comparison of price. It is a comparison of what the other person has to own, and that is the question to answer first. ## Comparing our own product - **Telvio bills per second** with no connection fee and credit that does not expire. Those three are genuine differentiators against most of this market and they are why the comparisons lead with the billing model rather than the rate. - **Telvio cannot reach emergency services and gives you no incoming number.** On a comparison against a service that does either, that is a decisive disadvantage and the page says so in the same voice as the advantages. - **Telvio is not cheapest everywhere.** Roughly twenty corridors are genuinely cheap; most of European mobile, China and much of Africa are expensive with us as with everyone, because the wholesale termination rate is what it is. - **Telvio needs an internet connection.** A calling card works from any phone with a dial tone; that is a real advantage in places where data is unreliable. ## What changes and what does not Prices in these comparisons carry the date they were checked. Wholesale rates move and retail follows, so treat specific figures in an older article as indicative. Structural properties are far more stable. A service that bills per minute has billed per minute for a decade; a service whose credit expires after 180 days has had that policy since it launched. Those are the findings worth relying on, and they are the ones the pages lead with. The market also consolidates. Skype's consumer calling has been wound down and smaller services disappear without much notice, which is a reason to weigh credit expiry more heavily than it looks: a balance that never expires survives a service you stop using, and one that expires in 180 days does not. ## Bottom line Every comparison here uses the same five properties — reaches phone numbers, billing increment, connection fee, credit expiry, registration — so the pages can be read against each other rather than each inventing its own criteria. The first question in any calling comparison is not price. It is whether the other person needs to own anything, and that single distinction separates the free messaging apps from the services that reach a telephone. ## Frequently asked questions What should I compare when choosing a calling service? Five things: whether it reaches ordinary phone numbers, whether it bills per second or per whole minute, whether it charges a connection fee, whether credit expires, and what registration demands of you. Every comparison here uses those same five so the pages can be read against each other. What is the difference between WhatsApp calls and a VoIP calling app? WhatsApp carries voice between people who both have WhatsApp, free, over the internet. A VoIP calling app connects to the public telephone network, so the person you call needs nothing installed and can be on a landline. They are different products that happen to share a category name. Is Skype still a good option for international calls? Skype's consumer calling has been wound down, which is the strongest argument in this market for weighing credit expiry heavily: a balance that never expires survives a service you stop using, and one that expires in 180 days does not. Comparisons involving Skype carry the date they were checked. Why do your comparisons have so few price rows? Because most services do not publish per-country pricing for most countries. Where a figure is not published we leave the row out rather than estimating — an invented number in a comparison is worse than a gap, because a gap is honest and a figure gets quoted. Do you compare Telvio honestly against competitors? Every comparison involving Telvio states what it does not do: it cannot reach emergency services, it needs an internet connection, and it is not cheapest on every corridor. Where a competitor wins a row, the row says so. A comparison the author's product wins on every line is an advertisement. How often are comparisons updated? Prices carry the date they were checked and move as wholesale rates move. Structural properties — billing unit, expiry, registration, whether the service reaches phone numbers — change far less often, which is why the pages lead with those rather than with a price. --- HTML version: https://telvio.app/compare/ Structured data for this site: https://telvio.app/api/v1/openapi.json · https://telvio.app/llms.txt Free to quote and reuse with a link back to the source URL above (CC BY 4.0).
