Design and Build
The Panasonic T21 featured a modest and straightforward design, with dimensions of 132 x 66 x 9.8 mm and weighing in at 140 g. This made it lightweight and relatively easy to handle. The device came in two classic colors, black and white, catering to users who preferred simplicity in design. The phone sported a dual SIM feature, allowing users to manage two numbers simultaneously, which was a practical advantage for separating personal and work communications.
