Cell phone service provider Hutchison Essar, a division of telecommunications giant Orange, on Friday became the second of India's wireless companies in a week to start selling "push to talk," the walkie-talkie style cell phone service. Tata Indicom has also introduced this feature recently.
Push-to-talk technology allows callers to connect to other cell phones with just the push of a single button, similar to a walkie-talkie. Only one person can talk at a time, and there is no need to dial a number.
