Review on 📻 Inrico T320 4g Internet Mobile Radio: Unlock GSM, WiFi Bluetooth, Zello Real PTT Android 7.0 Network Compatibility by Charles Osguthorpe

This is a good device if you sort through all the PTT options. Zello also steals the button when other apps are running, but a quick web search will help you fix that. What doesn't make this great is the reverse-action speaker, which allows me to either hear muted audio while waiting for the screen, or flip it over to hear the speaker when I can't look at the screen. If you're looking for a two-way radio-like experience, look for a device with a front-facing speaker.
