Design and Build
The NEC N21i features a compact and robust build, characteristic of the early 2000s mobile phones. Measuring 102 x 52 x 24.7 mm and weighing 120 grams, the phone is relatively lightweight and fits comfortably in hand, making it easy to handle and carry. The device accommodates a Mini-SIM card, which was the standard at the time. The aesthetics are simple, with a silver finish, giving it an understated yet familiar look.
