Design and Build
The Siemens A40 features a compact and sturdy design, typical of the period's mobile phones. With dimensions of 118 x 46 x 27 mm and a weight of 122 grams, it is relatively light and can be easily carried in a pocket or handbag. The device houses a Mini-SIM slot, hinting at its straightforward, single-connection functionality. The body design is durable with exchangeable covers available in several colors, including Royal Blue, Anthracite, and Raspberry Red, allowing for some personal customization of its otherwise utilitarian aesthetic.
