Connectivity and Communication:

The device supports GSM networks across 900, 1800, and 1900 bands, offering relatively broad international compatibility for its time. It lacks modern connectivity features such as Wi-Fi and GPS, but that's typical for phones of that era. Bluetooth 1.2 and an infrared port were sufficient for wireless data exchanges, although their speed and range limitations would be apparent today. The absence of a 3.5mm headphone jack and radio might limit its multimedia allure for music enthusiasts, but these features were not universally standard at the time.
