Design and Build
With dimensions of 108 x 46 x 14.3 mm and weighing just 106 grams, the Celkon C509 boasts a compact and lightweight design that fits comfortably in one hand or pocket. The phone features a dual SIM capability, allowing users to manage two numbers simultaneously, which was a particularly appealing feature for those needing separate lines for work and personal use. Encased in a straightforward black and red color scheme, the device has a classic, subdued aesthetic. A practical aspect of the design is the inclusion of a flashlight, which can be a handy tool in various situations.
