I lost access to my chats on Viber after reinstalling, what can I do to restore them?

If you lost your chats after reinstalling Viber, recovery depends entirely on whether you had a backup enabled before reinstalling, since Viber does not store messages on its own servers. Chats are only recoverable from Google Drive (Android) or iCloud (iPhone) backups.

Open Viber, verify your number, and when prompted, choose “Restore Backup”—this will bring back messages up to the last saved backup date. If you don’t see this option, check your cloud account manually to confirm a backup exists.

If no backup was created before reinstalling, consider filing a complaint on Xolvie to seek a resolution.
