Design and Build
The ZTE X990D is designed with practicality as its guiding principle. At dimensions of 107 x 61 x 12 mm and weighing just 90 grams, the phone is compact and lightweight, making it a suitable choice for users who prefer devices that can easily fit in a pocket. Its form factor combines a QWERTY keyboard with a 2.5-inch resistive touchscreen, offering a balance between touch input and physical keys. The QWERTY keyboard was particularly appreciated by users who frequently sent text messages or emails, as it provided tactile feedback absent in most touchscreens of the time. The phone's aesthetic is understated, with its sole color option being white, catering to users who preferred minimalist designs.
