Design and Build
The Siemens C35 was designed with practical compactness in mind, featuring dimensions of 118 x 46 x 21 mm, which ensured it easily fit into pockets or bags. The phone weighed a modest 110 grams, striking a balance between portability and hand-feel solidity. Its design employed a monochrome graphic display presenting at a resolution of 101 x 54 pixels, allowing up to five lines of text, and described by a 17:9 ratio—sufficient for basic telecommunication needs. An additional highlight of its interface was the fixed icons that provided users with simple navigation. The C35 accepted a Mini-SIM card, typical of phones from its era.
