Design and Build
The Amoi A9B is compact and lightweight, measuring 86 x 44 x 21 mm and weighing just 80 grams. Its diminutive size makes it convenient to carry around, fitting easily into a pocket or purse. The device uses a Mini-SIM card, a standard format for its time. The overall build gives it a robust feel despite its small size, characteristic of mobile phones during the early 2000s, prioritizing durability and portability.
