Design and Build
The O2 XDA Atom presents a compact design with dimensions of 102 x 58 x 18.5 mm, making it relatively portable for its time. Weighing in at 140 grams, it is on the heavier side compared to phones today, but it was considered fairly lightweight back then. The device accommodates a Mini-SIM card, with a straightforward silver finish. The form factor promotes a practical aesthetic, suited to professionals who required powerful communication tools within a portable shell.
