📰 Why this phone matters: This unit is a sealed Trium MT-250 Neptune blue, preserved exactly as Mitsubishi shipped it during the final years of the Trium mobile era. Still wrapped in its original factory shrink, the box presents a classic early 2000s clamshell design with a translucent blue flip and a frosted keypad housing that defined the playful aesthetic of Trium handsets. The packaging shows the simple monochrome display with the Trium logo, underlining the minimalistic UI that characterized Mitsubishi’s compact GSM range.
The side label confirms the exact variant: MT-250 Neptune blue with a Mitsubishi retail IMEI, CE0165 certification and an unbroken production batch code. Very little documentation exists for the MT-250 today, making this sealed example exceptionally rare. As Trium devices vanished from the market long before smartphones took over, complete unopened units almost never survived. This one stands as a pure, untouched snapshot of Mitsubishi’s design language, a lightweight clamshell aimed at style-focused users of its time. For collectors, it is a highly uncommon BNIB relic from a manufacturer whose mobile legacy has become increasingly scarce and desirable.
