Design and Build
The Bosch 909 Dual features a compact and straightforward design typical of late 1990s mobile phones. Its dimensions of 112 x 50 x 17 mm make it small enough to fit comfortably in the hand, with a weight of just 99 grams ensuring that it is light and portable. The device fits the era's trend with its use of a plastic body and a design that places functionality above flair. It uses a Mini-SIM card slot, which was standard at the time. The phone was available in three different colors, offering a small level of customization for users.
