Telegram vs Viber: which is better in 2026?
Short answer: choose Telegram if you live on several devices, want your chat history in the cloud, large files and groups of up to 200,000 members, channels and bots. Choose Viber if calls matter most: free audio and video calls with up to 60 people, end-to-end encryption on by default for chats and calls, and Viber Out for calling ordinary phone numbers. Both are free to message.

Privacy and encryption
Viber says end-to-end encryption is on by default for 1-on-1 calls, chats and group chats, so not even Viber can read them. Telegram encrypts everything it stores in its cloud and offers Secret Chats with end-to-end encryption and self-destructing messages for maximum privacy. If you want end-to-end encryption without thinking about it, Viber has it on by default; with Telegram you open a Secret Chat.
Devices and chat history
Telegram keeps your history in its cloud and its apps are standalone, so you read and write from phones, tablets and computers at once without keeping the phone connected, and the history takes no disk space on your device. Viber is built around the phone, with notes and reminders for things you want to keep.
Groups, channels and bots
Telegram groups hold up to 200,000 members, and channels and bots make it a tool for communities and teamwork. Viber groups hold up to 250 members with polls, quizzes, @mentions and reactions, and it also has Communities, Channels and AI bots.
Calls
Viber was made for calling: free Viber-to-Viber audio and video calls anywhere in the world, group calls with up to 60 people, and paid Viber Out for landlines and mobile numbers. Telegram describes itself as pure messaging, so calls are not its focus.
The verdict
Pick Telegram for several devices, big files, channels and bots. Pick Viber for calls and default end-to-end encryption. Many people keep both: Telegram for news channels and work chats, Viber for calling family. More messengers: best messaging apps.
