Design and Build
The J210 sports a compact and convenient design, featuring dimensions of 101 x 43 x 19 mm and a feather-light weight of just 74 grams. This makes it exceedingly easy to slip into a pocket or bag and carry around all day without notice. The phone's build is typical of early 2000s mobile devices, employing a solid body with minimalist curves that feel comfortable in the hand. It supports a Mini-SIM, which was the standard at the time, further highlighting its straightforward and classic design.
