Design and Build
The Philips W5510 is compact, measuring 116.2 x 63 x 13 mm and weighing 138.8 grams. It has a no-nonsense design, easy to hold and pocket. Its dimensions make it comfortable for one-handed use, which was practical for the era when display sizes had not yet hit the expansive designs of today. The dark gray finish offers a professional and understated look, while the device's durability is suggested by its slightly thicker profile compared to modern smartphones.
