Design and Build
The Philips 399 is compact, with a body dimension of 102 x 49 x 13 mm and a weight of just 80 grams. This makes it lightweight and easily portable, fitting comfortably into pockets or small bags. The phone uses a Mini-SIM card, which was standard for the time. Its design was offered in stylish colors—Matt Black, High Glossy Black, and Red—catering to those who appreciated both subtle and bold aesthetics.
