Design and Build
The MIO 8390 comes with a compact, lightweight body, measuring 99 x 51 x 24 mm and weighing 125 grams, making it quite ergonomic and pocket-friendly. It supports a Mini-SIM, in line with the mobile standards of its time. The phone's exterior is available in two color options: Dazzling silver and opulent red, allowing for some degree of personal aesthetic choice. The build focuses on functionality with simplistic elegance rather than the sleek designs seen in contemporary smartphones.
