BenQ P31 Sound and Connectivity

Sound and Connectivity

The phone includes a loudspeaker and supports vibration and downloadable polyphonic ringtones to alert users of calls and messages. There is no 3.5mm audio jack, which was a common omission in many early mobile phones, necessitating the use of proprietary or adapter solutions for personal audio. Connectivity options were cutting-edge for the era, including Bluetooth 1.1 and an infrared port, although the absence of WLAN was a significant limitation. Notably, the device does not support EDGE or any positioning technology, tethering the P31 to the slower GPRS data speeds available at the time.
