Karbonn KT21 Express Design and Build

Design and Build

The Karbonn KT21 Express is characterized by its compact and straightforward design, aimed at functionality over fancy aesthetics. The dimensions and weight, although not specified, conform to a typical feature phone structure, fitting comfortably in the hand and pocket. The phone supports dual SIM cards, both using the Mini-SIM format, which was the standard at the time, allowing users to easily switch between different networks or use separate personal and professional numbers.
