Push-to-talk is a transmission method that turns your phone into a walkie-talkie, of sorts. The type that only allows communication one-way at a time, so like an air traffic controller, you’ll have to say “over” after each sentence, and of course “over and out” when your conversation is done.
For cell users, push-to-talk cellular is supposed to give people a way to quickly broadcast a message to receiving handsets. If multiple handsets are hooked up, a team leader can speak to all of them without ringing each one up individually.
Some apps already emulate this function, like HeyTell and Zello, but the Sprint app uses the carrier’s Direct Connect push-to-talk service. Sprint says it has a million users on Direct Connect already (most on rugged handsets), and hopes the app will allow it to tap into a new user-base.
