Design and Build
The Sewon SG-2890CD has a compact and lightweight design, measuring 72 x 40 x 23 mm and weighing just 80 grams. Its small form factor was typical for early 2000s cell phones, allowing it to fit comfortably in the palm and easily slip into a pocket. The phone uses a Mini-SIM card and sports a simple clamshell or bar design, characteristic of many phones from that era.
