Design and Build
The i-mobile i858 features a compact design with dimensions of 120 x 67 x 12.8 mm. This modest size facilitated ease of handling and portability, with the phone's form factor being comfortable for most users. Unfortunately, the weight of the device is unspecified, but the dimensions suggest it was light enough for daily portability. The phone accommodates a Mini-SIM, another indicator of its placement in the older generation of smartphones.
