Viber for iPhone

App summary

Viber is a mobile messaging and calling app from Viber Media that lets people communicate using their smartphones and tablets. It provides text chats, multimedia sharing, and voice/video conversations over an internet connection rather than traditional cellular SMS or circuit-switched voice. The app is designed to make both everyday and international communication simple and affordable.

Network and calling options

• Subscribe to Viber Out to place calls to regular phone numbers at low per-minute rates.
• Use a Wi‑Fi connection or a mobile data plan to send messages and make calls — a stable internet connection is required.
• Calls and messages travel over the internet using VoIP technology instead of standard SMS or carrier voice channels.
• Host group chats and connect with many people at once from any location.

Messaging capabilities

• Send files and attachments directly through chats, such as documents or voice notes.
• Browse and use animated stickers and GIFs from Viber’s own store; paid sticker packs are available.
• Extend chat functionality by linking third‑party apps and services through chat extensions.
• Exchange text, photos, and video clips with individuals or groups.

Voice, video and privacy protections

Viber supports both high-quality audio calls and video conversations. All one-to-one and group communications are protected with end-to-end encryption so that only the intended recipients can decrypt the content. Encryption keys are specific to each conversation and kept so that message contents are not accessible to outside parties. These security measures cover calls, messages and shared media.

Group management and temporary chats

• Start secret chats with self-destruct timers that remove messages from participants’ histories after they’re viewed.
• Create Communities with administrator controls for larger interest-based groups.
• Mention members, pin important posts and reply to specific messages inside group conversations.
• Share your location or swap contact details directly in chats.
• Add up to 250 participants in a standard group for private discussions.

Why people use it

Viber combines free internet-based messaging and calling with extra mobile-friendly features such as rich media sharing, stickers, and group/community tools. It’s chosen by users who want flexible, secure communication beyond what default phone apps typically offer.
