Design and Build
The Samsung A400 showcases a minimalistic and utilitarian design with dimensions of 70 x 48 x 20 mm and a weight of 80 grams. Its petite size makes it convenient to fit into any pocket, and at just under three ounces, it is remarkably lightweight. The A400 uses a Mini-SIM card, which was standard at the time, further underscoring its dated yet functional design. Presenting a straightforward aesthetic, the phone includes four-way navigation keys, which were effective for menu navigation. The build is durable, tailored for users seeking a no-nonsense approach to mobile communication.
