Design and Build
The Motorola E390 showcased a compact design consistent with early 2000s mobile phones. With dimensions of 107 x 46 x 22 mm and a weight of 100 grams, its build conveyed both portability and sturdiness. The use of a Mini-SIM slot was standard for the era. While these dimensions might seem bulky by today's ultra-slim standards, the size was well-suited for the functional yet diverse needs of its time. A core element missing, indicative of earlier mobile phone designs, was any type of external loudspeaker or a 3.5mm headphone jack, emphasizing its use primarily for basic calling and messaging.
