Design and Build
The Siemens SL42 features a compact design with dimensions of 105 x 46 x 17 mm, making it easy to handle and store in pockets. Weighing only 88 grams, it was remarkably light for its era. The phone utilizes a Mini-SIM card and exudes a minimalistic style, characteristic of early mobile phones. Its body housing is sleek, which was appealing to users seeking a professional appearance.
