Step-by-step explanation:
When discussing brands that are compatible with Push-to-Talk (PTT), it's important to explain that PTT is a feature that allows a mobile device to be used as a walkie-talkie, with instant communication typically at the push of a button. Many mobile phones can support PTT either through built-in functionality or via an app. Here are four phone brands that are compatible with Push-to-Talk:
- Motorola
- Samsung
- Apple (iPhones with PTT apps)
- Kyocera
Motorola has a long history of integrating PTT functionality in some of their devices. Samsung offers devices that can be equipped with PTT services, often used in rugged environments. Apple's iPhones do not have native PTT, but they can use PTT applications available in the App Store, and Kyocera manufactures phones that come with PTT capabilities, designed for tough conditions and often used in industrial settings.
