Design and Build
The Sony Ericsson J230 boasts a compact and lightweight design, measuring 102 x 44 x 18 mm and weighing just 84 grams. Its compact dimensions make it highly portable, easily fitting into pockets or small bags without hassle. The phone's exterior is available in three distinct colors—Cosmo White, Cherry Red, and Deep Blue—giving users a small but appreciated level of customization. The phone employs a Mini-SIM format, common for devices of that time, which underlines its straightforward and utilitarian design approach.
