Design and Build
In terms of design, the Celkon C305 is compact and lightweight, measuring 105 x 43 x 15 mm and weighing just 73 grams. This makes it highly portable and easy to handle, fitting comfortably in the hand and pocket. The phone supports dual Mini-SIM slots, which was quite typical for feature phones of that time, enabling users to manage two different numbers or networks conveniently. A notable addition to its physical design is the built-in flashlight, which adds practical utility for everyday tasks in low-light environments.
