Audio and Connectivity
The P730's sound capabilities included vibration and downloadable polyphonic ringtones, which were common in phones of its era. However, it lacked a loudspeaker and a 3.5mm jack, which might be a limitation for users seeking to connect standard headphones or external audio devices. Connectivity options were rather limited: with no Bluetooth, Wi-Fi, or radio capabilities. However, it did feature an infrared port, a popular method at the time for transferring small files.
