Design and Build
The Motorola E378i is compact and somewhat sleek for its time, measuring 111 x 47 x 22 mm and weighing 102 grams. With its solid black finish, it provides a sturdy feel in the hand and is convenient to carry in a pocket. It supports the standard Mini-SIM, common for devices of its generation. Its design is fairly typical of mid-2000s mobile phones, with a simple interface and straightforward navigation keys.
