Design and Build
The design of the Samsung Rex 90 is functional rather than cutting-edge. Its dimensions, 113 x 61.9 x 11.9 mm, and unspecified weight suggest a compact phone that could easily fit into any pocket. The dual-SIM capability, a widely appreciated feature at the time, allowed for flexibility in managing two mobile numbers, catering especially to users who travel frequently or need separate lines for work and personal use. The device features a plastic build typical of its time, available in classic white and brown hues.
