Design and Build
The O2 XDA Terra showcases a classic design synonymous with mid-2000s smartphones. Measuring 109 x 59 x 17 mm and weighing 168 grams, its slightly bulky form factor reflects the technology standards of its release period. The inclusion of a full QWERTY keyboard aids in message typing and note-taking, catering primarily to professional users who need efficient text entry. The phone uses a mini-SIM form factor, which was standard at the time, adding to its vintage appeal today.
