How much data bandwidth does the app use?

The app consumes 20 KB (KiloBytes) per hour when idle. 

Zello will use between 12kbps and 45 kbps (kilo bits per second) when talking, depending on the connection type.

The audio encoder is chosen based on the connection type of both the sender and receiver.

If both are using WiFi, it will will use 45 kpbs. If either are using 2G, it'll switch to 12 kbps.

If using ZelloWork, the active data rate can be configured in the range between 8 kbps and 40 kbps.

Average monthly data usage is generally from 70-100 MB, although individual usage may vary.
