Design and Build
At first glance, the Siemens AF51 is a compact and lightweight device, measuring 79 x 41 x 19.6 mm and weighing only 80 grams. Its portability makes it highly convenient for users who need a no-fuss phone for basic communication. The body of the AF51 accommodates a Mini-SIM card and is available in two classic colors, Panther Black and Dolphin Grey. Its clamshell design is typical of the era, giving it a nostalgic appeal while effectively protecting the main screen from scratches and damages when closed.
