The Siemens AL21 sports a compact and lightweight design, ideal for users who prioritize portability. With dimensions of 86.8 x 45.8 x 19.2 mm and a weight of just 78 grams, this phone fits comfortably in the palm, pocket, or handbag. The handset accommodates a Mini-SIM, consistent with its era, and features a simple, no-nonsense plastic body. Available in two colors, Red Temptation and Black Magic, the AL21 manages to maintain a modest yet appealing aesthetic.
