A free program for android
You may interact with individuals from all around the world in high-quality audio with CB Radio Chat, which is a live voice communicator and messenger that is both free and entertaining to use. You can connect with your existing acquaintances and make new ones by just pressing the blue button, just like you would with a walkie-talkie or a Push To Speak device (PTT). CB Radio Chat requires users to have an internet connection (WiFi, 3G, 4G, EDGE, or GPRS) in order to send and receive audio (max 11MB per hour). It is possible to utilize it right now, and registration is not required to do so. The CB Radio Talk service is very much like a group or conference call.
