Design and Build
The Bird S669 features a compact and minimalist design, measuring 104 x 45.5 x 15.7 mm. Its lightweight build, weighing just 75 grams, made it exceptionally portable and easy to handle. The device housed a Mini-SIM slot, typical for phones of that era, allowing for straightforward cellular connectivity. Despite its simplicity, the phone's availability in three color variants—Silver, Blue, and Red—provided some level of personalization and aesthetic appeal.
