Our verdict

Viber suits people who message and call friends and family in other countries, especially if they also want communities or calls to regular phone numbers. The trade-offs: the free version shows ads, Viber Plus has no published price, and Trustpilot sits at 1.3/5 with complaints about account blocks, billing and support.

Best for: People whose contacts already use Viber and who need cross-border calls and chat

Skip it if: People who want an ad-free app without paying

Pros

  • End-to-end encryption for personal chats, group chats and one-to-one calls, per Viber's security page
  • Group video calls with up to 60 people and group chats up to 250 members, per the Google Play description
  • Apps for iPhone, Android, Windows, Mac and Linux, with chat syncing across devices

Cons

  • The free version has ads; turning them off requires Viber Plus
  • Trustpilot 1.3/5 (357 reviews): complaints about account blocks, billing and support

Experience & key features

What Viber is

Viber is a messaging and calling app run by Viber Media S.à r.l., part of the Rakuten group. According to Wikipedia, it launched on iPhone on 2 December 2010 in Tel Aviv, Rakuten bought it for about 900 million USD in February 2014, and the company was renamed Rakuten Viber in 2017. The website says the app runs on Android, iPhone, iPad, Windows, Mac and Linux.

Key features

Per the Google Play description, Viber supports messages, photos, files, voice and video calls, group video calls with up to 60 people, group chats up to 250 members with polls, @mentions and reactions. It also has Communities, channels, disappearing messages, hidden chats, and editing or deleting sent messages. Viber Out lets you call regular phone numbers in countries where the service is available, through a single-destination subscription or purchased minutes.

Pricing and Viber Plus

Basic use is free but with ads. Viber Plus is a monthly or annual plan that removes ads and adds editing or deleting messages without a trace, invisible mode and free access to paid stickers. The help page gives no price and says to check in the app; the annual option may not be available everywhere. On the US App Store, Viber Out credit packs cost 0.99–9.99 USD, and monthly Viber Out subscriptions are 1.99 USD (USA) or 5.99 USD (worldwide).

More analysis

Compared with alternatives

Viber competes directly with WhatsApp, Telegram and Signal. What sets it apart is Viber Out for regular phone numbers and its Communities. Worth weighing: ads in the free version, the low Trustpilot score and regional blocking — Wikipedia records that Roskomnadzor blocked Viber in Russia on 13 December 2024.

Cancellation & refunds

Subscriptions auto-renew until you cancel through the store you bought from (Google Play, App Store or desktop); after cancelling you keep the benefits until the billing period ends. Subscriptions do not move between Android and iOS: you cancel on the old platform and subscribe again, and leftover days are not refunded. No separate refund policy was found in the pages reviewed.

Privacy

The privacy policy (updated 23 September 2026) says Viber collects identifiers such as phone number, name or date of birth if provided, photo, device identifiers, activity data and a general location estimated from IP address; GPS only with permission. Viber states it does not read or listen to the content of private messages and calls; messages are deleted once delivered, or after 14 days if delivery fails. Customer support records are kept for 10 years and call and activity records for 24 months. Device identifiers, age range, inferred gender and a reduced IP address may be shared with advertising partners for personalised ads, and can be opted out of in privacy settings. If you allow contacts access, Viber processes address-book names and numbers, including those of non-users. Data may be stored and processed worldwide, including the US, Asia, Europe, Russia, Australia and Brazil. Viber's security page says personal chats and group chats and one-to-one voice and video calls are end-to-end encrypted; Google Play says it is on by default for one-to-one chats, group chats, voice and video calls between Viber users. The service is not intended for children under 13.

Scores

Ease of use
8.0
Why this score

Phone-number sign-up with automatic contact matching; App Store 4.6/5 across 831,000+ ratings. Trustpilot reviews mention activation failures.

Features
8.0
Why this score

Chat, voice and video calls, groups, Communities, channels, disappearing messages, Viber Out, over 55,000 stickers (per the Google Play description) and desktop apps for Windows, Mac and Linux. Viber Out sets it apart; otherwise nothing is clearly ahead of the leading peers.

Value for money
7.0
Why this score

Core features are free but come with ads, whereas WhatsApp and Signal carry none. The help page lists no Viber Plus price; Viber Out is charged separately, from 0.99 USD per credit pack on the US App Store.

Performance
7.0
Why this score

Google Play 4.1/5 across 16.6 million reviews suggests broad satisfaction. Still, several prominent 2026 Google Play reviews describe messages and calls failing or dropping (one names Myanmar and Thailand), and Trustpilot reviewers report Viber Out calls cutting out.

Support
5.0
Why this score

There is a help center; live chat is only for Viber Plus subscribers and only in English. Trustpilot reviewers describe missing verification codes, unexplained account blocks and unexpected charges, and the company has replied to 26% of negative reviews.

Privacy & security
6.5
Why this score

End-to-end encryption is on by default for chats and calls between Viber users. Downsides: sharing data with ad partners, 10-year support records, processing in many regions.
