Design and Build
At a compact size of 106 x 49 x 22 mm and weighing only 95 grams, the Philips Fisio 121 is notably lightweight and convenient to carry. The shell of the phone is somewhat bulky by today's standards but was quite manageable at the time. The use of a Mini-SIM card follows the era’s norms, allowing for straightforward installation and setup. The phone was available in three color options: Storm Black, Whale Blue, and Opal White, offering slight personalization choices to users.
