Design and Build
The Bird D720 sports a compact and lightweight build, with dimensions of 100 x 46 x 15.9 mm and a weight of just 93 grams. This made it an easily pocketable device, convenient for everyday carry. The phone's exterior was available in several colors, including Silver, Green, and Blue, giving users a few aesthetic options. It utilizes a Mini-SIM, typical of the phones during that time period, and incorporates a sturdy design for what was expected from mobile devices back then.
