Users can engage in private conversations with contacts or join public channels with up to 6000 users without experiencing significant delays. Additionally the app supports various connectivity options including WiFi 2G 3G or 4G mobile data which enhances its reliability across different network conditions. Another feature contributing to the app's reliability is the call alert function which notifies users of incoming calls ensuring they never miss an important message. Furthermore Zello offers voice history allowing users to review past communications at any time enhancing the overall reliability of message delivery. With these features Zello ensures that users can rely on the application for fast and dependable communication regardless of their location or network environment.

Media sharing support is an essential aspect of modern communication applications enabling users to exchange various types of content beyond just text or voice messages. Zello PTT Walkie Talkie provides robust media sharing capabilities that enhance user interaction and engagement. One notable feature is the ability to send images through the app allowing users to share visual information instantly.
