TCL Optus X Start TD-LTE AU (TCL U3A)

The TCL Optus X Start feels compact in the hand, measuring just 65.7 mm wide, 137.6 mm tall and 9.8 mm thick while weighing only 134 grams.

A 2000 mAh battery provides enough power to get through a typical day of moderate use, and the overall dimensions keep the device pocket‑friendly while still offering a usable display size.
