Once a channel is created, its name cannot be changed. If you need a new name, you must create a new channel. Channel Moderation Guidelines - Zello Support
Zello channels are not encrypted end-to-end in the consumer sense. While private channels are secure from the general public, Zello (the company) could theoretically access the audio. Furthermore, recordings can be made by any user in the channel, creating a record of conversations that radio waves do not inherently leave.
Zello gained international fame during Hurricane Harvey in 2017 and subsequent natural disasters. When cell towers become overloaded and voice calls fail, Zello’s low-bandwidth data packets can still get through.
Designed for smaller, agile groups (like a security team at an event), team channels allow for quick invites via QR codes or links and offer distinct administrative controls for roles and dispatching.
A Zello channel is not just a tech utility; it is a digital society with a rigid hierarchy.
