    As a lesser-known platform, there may be concerns about its long-term sustainability, continued development, and ongoing support.

    Viber calls and messages are dependent on internet connectivity, limiting its functionality in areas with poor or no internet access.

  • Quality of Service
    The quality of voice and video calls can be inconsistent and is highly dependent on the speed and stability of the internet connection.
  • Privacy Concerns
    Despite end-to-end encryption, some users remain concerned about the collection of metadata and potential privacy issues.
  • In-App Purchases
    While basic features are free, Viber offers in-app purchases for additional services such as premium stickers and Viber Out credits.
