Design and Build
In terms of design, the BenQ-Siemens C31 sports modest dimensions of 99.8 x 46.7 x 16.7 mm, making it compact and easily portable. Weighing only 86 grams, it is remarkably light, a characteristic feature of many phones from that era. The phone's body accommodates a mini-SIM, in contrast to the more prevalent nano-SIM standards today. Available in two color options, SilverShine and GraphiteGloss, the phone offers a classic metallic finish appealing to those who preferred a simple yet elegant look.
