WND Wind DUO 2200 Connectivity and Audio

Connectivity and Audio

The Wind DUO 2200 supports GSM networks across 900, 1800, and 1900 MHz bands. Its connectivity features include Bluetooth 1.2 with A2DP support for wireless audio, although it lacks more modern provisions like WLAN, GPS, and high-speed EDGE. The absence of a 3.5mm audio jack suggests an emphasis on compactness at the expense of traditional headphone connectivity, though the built-in loudspeaker and downloadable MP3 ringtones offer some audio versatility.
