Audio and Connectivity
Audio features on the VK500 are basic, with no loudspeaker or 3.5mm jack for headphones. The device supports vibration and downloadable polyphonic ringtones for alerts. Connectivity options are minimal, lacking modern conveniences such as Bluetooth, Wi-Fi, or even a radio. The absence of these features aligns with its intended role as a basic communication tool rather than a multimedia or internet browsing device.
