Same idea – call real phone numbers abroad. But without the app requirement, without per-minute rounding, and without tying your balance to a device.

Short answer
Viber Out is a good choice for personal calls from a smartphone that already runs Viber. FluffyCall is the better fit if you want to call from a browser – on a computer, tablet or phone – without installing anything, pay for the exact seconds you talk, and get an invoice for your business.
An honest look at a popular service
Viber Out is a solid option for calling landlines and mobiles abroad. The per-minute rates are competitive for many destinations, and the app is already on many phones. For personal calls from your smartphone, it works.
But Viber Out has three structural limitations that become real problems for frequent or business callers:
1. Your balance is tied to the app. Viber freezes World Credit after six months without use. You can unfreeze it, but only from inside the Viber app. Credit is lost if you deactivate Viber, or if you remove the app and don't reinstall it for more than three months. Minutes from a Minutes Country Plan don't roll over: the minute limit restarts every month while the monthly fee keeps running until you cancel. (Source: Viber Support, October 2026)
2. You need the Viber app. Every device you want to call from needs Viber installed. On company laptops and managed devices, IT departments often restrict third-party app installations. Browser-based alternatives eliminate this friction entirely.
3. Every call is rounded up. Viber calculates call duration per minute, not per fraction of a minute. On a 40-second call you pay for a full minute. Whether a call is long or short, that rounding is added to every single call. (Source: Viber Support, October 2026)
FluffyCall was built to solve exactly these problems. Same core function – calling real phone numbers abroad – but without the app dependency, without per-minute rounding, and with a balance that lives in your account rather than on a device.
Both services let you call real phone numbers abroad – here's how they differ
| Feature | Viber Out | FluffyCall Recommended |
|---|---|---|
| App required | Yes – Viber app on phone or desktop | No – any web browser on computer, tablet or phone |
| Credit validity | Frozen after 6 months without use (can be unfrozen); lost on deactivation or after 3+ months uninstalled | No expiry date – stays on your account as long as it exists |
| Unused minutes | Minutes Country Plan minutes restart every month, no roll-over | No plans – credit only, always available |
| Billing granularity | Per minute (rounded up) | Per second (exact) |
| Registration requires | Mobile number + app | Business email only |
| Works on managed devices | Only if the app may be installed | Yes – browser only, no IT setup |
| Calling plans | Country plans and a World Unlimited Plan (60 countries, fixed monthly price) | None – pay-as-you-go only |
Price per minute is only part of the picture
Viber's per-minute rates are lower than ours on many routes. On popular destinations such as the US, the UK and Germany, the gap for landlines is around one to two cents per minute; on some long-distance routes it is larger. What you get in return shows up in the situations below.
Built for professional use from day one
What you get beyond the call itself
FluffyCall is registered with the Bundesnetzagentur as a telecommunications provider under German telecommunications law.
Every top-up produces a proper invoice with German VAT, containing all details required under German tax law – so your accountant can book it and you can deduct the input tax. Data processing follows the GDPR.
If you need international calls as a business expense rather than a private purchase, that is the part worth checking before you pick a provider.
We believe in honest comparisons
Viber Out is a good fit if you already use Viber daily for messaging, call exclusively from your personal smartphone, keep the app installed, and don't need an invoice for your business.
For personal, high-frequency calling from a smartphone to a single country, Viber Out's fixed-price plans can offer genuine value – and if the lowest price per minute matters most, Viber is often a cent or two cheaper.
FluffyCall is the better choice when you want to call from any browser – including a work computer – want per-second billing on long and short calls alike, need browser-based access without app installations, require proper invoices for your business, or want your balance reachable from any browser without an app.
No app. No phone number. Just your browser.
Viber Out vs FluffyCall – common questions answered
Not automatically. Viber freezes World Credit after six months without use – you can unfreeze it from inside the Viber app. Credit is lost if you deactivate Viber or remove the app and don't reinstall it for more than three months. FluffyCall credit has no expiry date and stays on your account as long as the account exists.
Per minute, often yes. On popular routes such as the US, the UK and Germany, Viber's landline rates are around one to two cents per minute lower; on some long-distance routes the gap is larger. FluffyCall bills per second instead of per started minute, needs no app and no subscription, and issues an invoice for every top-up – which matters more for short calls and business use than the headline rate.
No. Viber Out is a feature within the Viber messaging app. You need to download and install Viber on your smartphone or desktop computer to use Viber Out. FluffyCall works directly in any modern web browser – no download or installation needed.
Rates start at €0.03 per minute and are shown before you dial. There is no contract lock-in, no monthly fee and no connection charge. Billing is per second, so a 40-second call costs 40 seconds – not a rounded-up minute. You pay from prepaid credit that has no expiry date.
Viber's own support pages do not list a per-call connection fee. What can add cost is buying credit through an app store, where currency conversion and transaction charges apply – Viber recommends buying directly on their website to avoid this. FluffyCall charges no connection fee either. The difference that does affect your bill is per-second billing versus Viber's rounding up to the next full minute.
FluffyCall is built for business users: an invoice for every top-up, calls from any browser without installing an app on managed devices, and registration with a business email instead of a phone number. FluffyCall runs on servers in Germany; calls are connected by Telnyx in the USA under the EU-US Data Privacy Framework and EU Standard Contractual Clauses. Viber Out is designed mainly for personal calls from the Viber app.
Yes. Both FluffyCall and Viber Out support calls to landline and mobile numbers worldwide. Rates typically differ between landline and mobile calls for both services. All rates are published transparently on each provider's website.
No. FluffyCall registration uses your business email address. You do not need to provide a personal phone number. Viber requires a mobile phone number for account creation and verification.
No. There is no subscription, no minimum term and no monthly fee. You top up from 10 euros, pay per second, and your credit has no expiry date.
Yes. FluffyCall runs in your web browser, so you can call landlines and mobiles in 200+ countries from a laptop or desktop computer. No app, no SIM card and no software installation – you only need a microphone and an internet connection.
Yes. FluffyCall runs in the web browser, so it works on computers, tablets including the iPad, and smartphones. You need a microphone, which phones and tablets have built in, and an internet connection. No app download is required on any device.
