What people say
about Telvio
Reviews of Telvio live on platforms we do not control, which is the only place a review is worth reading. Here is where to find them, and how to add yours.
Three places, and what each one is for
Pick the one that matches how you use Telvio. A review on any of them is public, permanent and outside our reach.
Trustpilot
The general-purpose one. Anybody can write there, no account with us required, and the review sits on Trustpilot's domain rather than ours — we cannot edit it, reorder it or take it down.
Best for: the whole experience — price, call quality, whether the credit did what you expected.
App Store
Reviews and star ratings for the iPhone, iPad and Mac app. The link opens the rating sheet on a device that has Telvio installed; on a desktop browser it opens the listing instead.
Best for: the app itself — the dialler, the contacts screen, how it behaves on your device.
Google Play
Ratings and reviews for the Android app. Google takes reviews only inside the Play Store app on your phone, so there is no web form to link to — open Play on the device, find Telvio, and rate it there.
Best for: Android-specific behaviour — audio routing, Bluetooth, your carrier's data connection.
What makes a review useful to the next reader
A rating on its own tells somebody almost nothing about a calling app. Four details do most of the work.
Which country you call
Call quality on an internet call is mostly a property of the route to that country, not of the app. "Clear to Manila, five calls in a row" is worth more than "good quality", because the person reading it is trying to call one specific place.
What you were on
Home wifi, café wifi, 4G on a foreign SIM — they behave differently, and a review that names the network tells the next reader whether your experience is the one they will have.
What it replaced
Roaming, a calling card, a different app. The comparison is the part nobody can look up: what you were paying before, and what the same call costs now.
What went wrong
If a call failed, say what the app showed and which number you dialled. That is a better bug report than most, and it is the kind of review that gets a real reply rather than a thank-you.
What we do, and do not do, with reviews
Telvio is a small app and a young one. There is no large pile of reviews to point at, and manufacturing one would be both against every platform's rules and obvious to anybody reading closely — a brand-new product with three hundred five-star reviews is a product to be suspicious of.
So the position is simple. We ask, we do not pay, and we do not choose who gets asked.
Something to say that is not a review
If a call failed, credit did not arrive, or you want your data deleted, write to us instead of filing a one-star review and waiting. Support reaches a person, and most of what lands there is fixed the same day.
Email support — [email protected]Nothing is bought, nothing is traded
No credit, no free minutes, no discount in exchange for a review or a rating. Incentivised reviews are banned by Trustpilot, Apple and Google, and a review that cost us $1.99 is worth exactly that to a reader.
No review gate
Some apps ask how you feel first and route only the happy answers to the store. We do not. Everyone gets the same link to the same public page, whatever they think of us.
Negative reviews stay up
We reply to them in public and fix what can be fixed. We report a review only if it is fraud or abuse under the platform's own rules — never because it is unflattering.
Questions about reviews
Is Telvio a legitimate app?
Yes. Telvio is published by Vast Flow, LLP and distributed through the Apple App Store and Google Play, both of which review an app before it is listed and again on every update. Calls are carried by a licensed telecoms carrier, and outbound calls show the caller ID +14342800044, which is registered to us and published on this site. The reviews linked from this page sit on platforms we do not control, which is the check worth making on any unfamiliar app.
Do I need an account with Telvio to leave a review?
No. Trustpilot needs a Trustpilot account, and the App Store needs an Apple Account, but neither is connected to us — the app itself has no registration, no login and no password. That is also why we cannot see who wrote which review.
Do you pay for reviews?
No. No money, no credit, no free minutes and no discount, in either direction. Paying for reviews is against the rules of every platform on this page and would get the profile penalised or removed, which is the practical argument on top of the obvious one.
Will you delete my review if it is negative?
No, and on Trustpilot and the app stores we could not even if we wanted to — a business can reply to a review and can report one for breaking the platform's rules, but cannot remove it. We report only fraud and abuse, and everything else stays up with a reply under it.
Can I change or delete a review I already left?
Yes, on all of them. Trustpilot lets you edit or delete your own review from your Trustpilot account at any time. The App Store and Google Play each allow one review per app per account, and writing a new one replaces the old. None of that goes through us.
My call did not connect. Should I write a review about it?
Write to support first, at the address on this page. A failed call usually has a specific cause — a number typed in the national format, a destination we do not carry, a network that blocks the audio — and every one of those is something a reply can solve in a few minutes. Review us afterwards, either way.
Try it before you review it
One free minute, no card and no account. Then decide what to write.
Download TelvioWhy the reviews themselves are not printed on this page
Almost every company site with a reviews page shows the reviews on it: a carousel of five-star quotes, a big average, a row of logos. We link out instead, and the reason is worth stating because it looks like a missing feature rather than a decision.
A quote reprinted on our own site has been through our hands. We chose which ones to show, in what order, and when to stop updating them — and a reader has no way to check any of that. The same review read on Trustpilot sits next to the ones we would not have chosen, with a date on it and a profile behind it. It is the same words carrying far more information.
There is a second, smaller reason. Showing reviews in place means loading a widget from the review platform, which is a third-party script on every page it appears. The cookie statement for this site says it runs one third-party tool and sets no cookies of its own. That sentence is easy to keep true by not adding the widget, and awkward to keep true any other way.
How to read a review of a calling app
Ratings for calling apps are noisier than ratings for most software, and the noise has a specific shape. A call that fails is dramatic — the person on the other end is a parent or a landlord, and the failure happens at the worst possible moment — so a single bad call produces a one-star review far more often than a hundred good ones produce a five-star one. Read the distribution accordingly.
The second thing to look for is whether a review names a destination. Call quality over the internet is mostly a property of the route between the carrier and the local network at the far end, and those routes differ by country and sometimes by mobile operator within a country. A review that says calls to Georgia are clear and a review that says calls to the Philippines drop can both be accurate on the same day, about the same app.
Third, separate the app from the arithmetic. Complaints about a dialler, a contacts list or a confusing screen are about software, and software gets fixed. Complaints about a price are about a rate sheet, which is published in full at our rates page and can be checked before you spend anything — a free minute costs nothing and settles the question faster than any review can.
What we actually do with what people write
Reviews and support mail get read by the same two people, and the useful ones tend to arrive as a specific complaint rather than a rating. A run of failed calls to one country led to the dialler learning national trunk prefixes properly: a Japanese number typed the way it is typed in Japan now gets converted before it is dialled, instead of failing quietly and looking like a broken app.
Other feedback changes wording rather than code. A recurring confusion about what happens when credit runs out during a call, or about whether the free minute applies to a particular destination, is a sign the screen is wrong, not that the reader is. Those are cheap to fix and nobody files a bug report about them — they show up in reviews and nowhere else.
What a review cannot do is diagnose your call. We cannot see who wrote a review, cannot tie it to an account, and the app deliberately holds no personal data to tie it to. A call that will not connect is solved in a reply to an email, usually in one round trip; the help centre covers the common causes if you would rather not wait for one.
The star rating we do not show you
You will notice there is no average rating anywhere on this page, and no star graphic in Google's results for it. That is deliberate too. Google's own guidance treats review markup a site writes about itself as ineligible for rich results, and treats a fabricated one as spam; marking up an average we calculated ourselves would be either ignored or penalised, and would tell a reader nothing they should believe in any case.
The ratings that exist are on the pages linked above. Trustpilot computes its own, Apple and Google compute theirs from verified purchases and installs, and none of the three asks our permission. Where a number here is ours — a rate, a caller ID, a billing rule — it is published with enough detail to be checked against the app itself, which is the only kind of claim worth making on a page about trust.
Bottom line
Read reviews of Telvio on Trustpilot, the App Store and Google Play. Write one wherever you use the app: on Trustpilot for the whole experience, in the store for the app on your device. Nobody is paid for a review, nobody is filtered out of leaving one, and negative reviews stay up with a reply under them.
If something is broken, support fixes it faster than a review does. Write to [email protected] first, and review us afterwards with the outcome.
Frequently asked questions
Where is Telvio's star rating?
On the platforms that calculate it: Trustpilot, the App Store and Google Play, all linked from this page. Telvio does not publish an average rating on its own site, because an average a company computes about itself is not evidence, and marking one up for search results is against Google's structured-data guidelines.
Why are the reviews not embedded on the page?
Two reasons. A review reprinted by the company that received it has been through a filter the reader cannot see, and an embedded review widget is a third-party script on a site that currently runs one analytics tool and sets no cookies of its own. Linking out costs a click and keeps both problems away.
Does Telvio ask customers for reviews?
Yes, and in the plainest way available: a link to the public review page, sent to anybody who asks where to leave feedback, with no filtering by how happy they seem. What we never do is offer credit, free minutes or a discount in exchange, which is banned by Trustpilot, Apple and Google alike.
Are reviews shown in my language?
That is up to the platform. Trustpilot shows reviews in the language they were written in and lets you filter by country; the App Store shows reviews from your store's region by default. This page is published in thirty languages, but the reviews it points at are not ours to translate.
Can a business review Telvio?
Yes. Trustpilot takes reviews from anybody, including a company reviewing a supplier, and the app stores take one from any account that installed the app. There is no profile on the business-software review sites, and there will not be: those catalogue products bought by a buying committee — seats, admin consoles, procurement — and Telvio has no account, no seats and nothing to administer. For a team deciding whether to use it, the rate sheet and the published list of what the app deliberately cannot do answer more than a review site would.
I was asked to review Telvio by someone claiming to work for it. Is that real?
We write from one address, [email protected], and we never offer anything in exchange for a review. If a message promises credit, a gift card or a prize for reviewing Telvio, it did not come from us — forward it to that address and we will report it to the platform it names.
