Digital phones are more reliable than analog phones. The digital signals are easier to produce and the technology is more reliable than that of analog signal.
Radio waves are used in cell phones to transmit and receive signals by converting sound and data into electromagnetic waves that travel through the air to nearby cell towers. These towers then relay the signals to other cell phones or the internet, allowing for communication between devices.
