Design and Build
Physically, the Siemens U15 sports a rather bulky form factor, measuring 136 x 53 x 24 mm with a weight of 140 grams. These dimensions are indicative of early 3G phones which often sacrificed slimness for technological capability. The device is designed to accommodate a mini-SIM and presents a somewhat utilitarian aesthetics typical of early 2000s mobile devices. While its build might appear cumbersome by modern standards, it reflects the era's need to balance emerging technology with the physical constraints of the time.
