What is a dual mode cellular phone?
Dual mode means that the phone works both in analog and digital modes, which are two different frequencies. The very old phones are analog only phones. Most of the new phones are either digital or dual mode. A cell phone is usually in digital mode unless the digital signal is very weak or not available, then the phone automatically switches to analog mode. Mostly near the metropolitan areas, the phone will remain in digital mode. When you get further away from the city, you will need analog service. Digital sound is much clearer than analog.
