GB WhatsApp Pro is a modified version of the official WhatsApp application, offering enhanced features and customization options. Unlike the standard WhatsApp, GB WhatsApp pro allows users to personalize their messaging experience with themes, fonts, and privacy settings. It also includes advanced functionalities like anti-ban protection, dual account support, and increased media-sharing limits. However, it is not an official app and is developed by third-party developers, which may pose security risks.
